“…The key challenge is to increase the strength of SO coupling without increasing the plasmon damping, due to dissipative losses. The main strategies currently pursued with conventional FMs, namely without increasing the intrinsic SO coupling, are illustrated in figure 15 and include the design and fabrication of: periodic arrangements of MP nanoantennas [105]; 3D pure FM and composite FM/NM and FM/D/NM nanostructures [106]; and 'meta-atoms', i.e. heterogeneous units comprising of multiple nanoantennas placed in proximity to enable their near-field interaction.…”

Building upon the success and relevance of the 2014 Magnetism Roadmap, this 2017 Magnetism Roadmap edition follows a similar general layout, even if its focus is naturally shifted, and a different group of experts and, thus, viewpoints are being collected and presented. More importantly, key developments have changed the research landscape in very relevant ways, so that a novel view onto some of the most crucial developments is warranted, and thus, this 2017 Magnetism Roadmap article is a timely endeavour. The change in landscape is hereby not exclusively scientific, but also reflects the magnetism related industrial application portfolio. Specifically, Hard Disk Drive technology, which still dominates digital storage and will continue to do so for many years, if not decades, has now limited its footprint in the scientific Topical ReviewOriginal content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Also, more and more work is occurring in which complex topologies of magnetically ordered states are being explored, hereby aiming at a technological utilization of the very theoretical concepts that were recognised by the 2016 Nobel Prize in Physics.Given this somewhat shifted scenario, it seemed appropriate to select topics for this Roadmap article that represent the three core pillars of magnetism, namely magnetic materials, magnetic phenomena and associated characterization techniques, as well as applications of magnetism. While many of the contributions in this Roadmap have clearly overlapping relevance in all three fields, their relative focus is mostly associated to one of the three pillars. In this way, the interconnecting roles of having suitable magnetic materials, understanding (and being able to characterize) the underlying physics of their behaviour and utilizing them for applications and devices is well illustrated, thus giving an accurate snapshot of the world of magnetism in 2017.The article consists of 14 sections, each written by an expert in the field and addressing a specific subject on two pages. Evidently, the depth at which each contribution can describe the subject matter is limited and a full review of their statuses, advances, challenges and perspectives cannot be fully accomplished. Also, magnetism, as a vibrant research field, is too diverse, so that a number of areas will not be adequately represented here, leaving space for further Roadmap editions in the future. However, this 2017 Magnetism Roadmap article can provide a frame that will enable the reader to judge where each subject and magnetism research field stands overall today and which directions it might take in the foreseeable future.The first mater...

“…Hence, it is difficult to achieve ferromagnetic and plasmonic behaviors in the same material. Only recently, nanostructures of Ni [14][15][16][17][18][19][20] Ni/Co [21] and permalloy antidots [22] have been reported to exhibit surface plasmons in combination with their well-known ferromagnetic character at room temperature. However, the intensity of the plasmonic resonance in these type of materials is fairly weaker than for noble metals as Au or Ag where the electromagnetic field can be increased locally up to 80 times upon excitation of surface plasmons [23].…”

Abstract:We have designed and fabricated a nanodevice exhibiting simultaneously ferromagnetic properties of nanostructures with plasmonic properties of continuous films. Our device consists in an array of nanomagnets on top of a continuous plasmonic film. The patterned nanomagnets magnetic state is single domain and well-defined shape anisotropy. Despite the presence of the patterned media on top of the Au film, the system exhibit surface plasmon resonance characteristic of a continuous film, i. e., propagating surface plasmonpolaritons.

“…SPPs are electromagnetic waves that propagate along the interface between metal-dielectric or metal-air media. These systems show significant future promises, especially, in fulfilling the demand for ultra-fast sensing and detection, higher signal-to-noise ratio (SNR) sensing, and miniature devices, which are needed in monitoring biological and chemical changes taking place in solutions with extremely low protein concentration [11][12][13][14][15][16]18,170,171]. This magnetic field enhanced sensing utilizes Surface plasmon resonance (SPR) in the presence of H field, which is the optical excitation of charge electron densities.…”

“…Ferromagnetic (FM) multilayered films are important materials because they exhibit interesting physical properties such as giant magnetoresistance (GMR) [1][2][3][4][5][6], magnetic anisotropy (MA) [7][8][9], tunneling magnetoresistance (TMR) [10], surface plasmon-resonance (SPR) and giant magneto-reflectivity (GMRE) [11][12][13][14]. These properties are very sensitive to the microstructure of the multilayered film.…”

Ferromagnetic Multilayers: Magnetoresistance, Magnetic Anisotropy, and Beyond

Abstract:Obtaining highly sensitive ferromagnetic, FM, and nonmagnetic, NM, multilayers with a large room-temperature magnetoresistance, MR, and strong magnetic anisotropy, MA, under a small externally applied magnetic field, H, remains a subject of scientific and technical interest. Recent advances in nanofabrication and characterization techniques have further opened up several new ways through which MR, sensitivity to H, and MA of the FM/NM multilayers could be dramatically improved in miniature devices such as smart spin-valves based biosensors, non-volatile magnetic random access memory, and spin transfer torque nano-oscillators. This review presents in detail the fabrication and characterization of a few representative FM/NM multilayered films-including the nature and origin of MR, mechanism associated with spin-dependent conductivity and artificial generation of MA. In particular, a special attention is given to the Pulsed-current deposition technique and on the potential industrial applications and future prospects. FM multilayers presented in this review are already used in real-life applications such as magnetic sensors in automobile and computer industries. These material are extremely important as they have the capability to efficiently replace presently used magnetic sensors in automobile, electronics, biophysics, and medicine, among many others.
