Surface plasmon polaritons provide a unique opportunity to localize and guide optical signals on deeply subwavelength scales and can be used as a prospective information carrier in highly integrated photonic circuits. Dielectric‐loaded surface plasmon polariton waveguides present a particular interest for applications offering a unique platform for the realization of integrated active functionalities. This includes active control of plasmonic propagation using thermo‐optic, electro‐optic, and all‐optical switching as well as compensation of propagation losses. In this review, the principles and performance of such waveguides are discussed and the current status of the related active plasmonic components which can be integrated in silicon or other nanophotonic circuitries is summarized. A comparison of dielectric‐loaded and other plasmonic waveguides is presented and various material platforms and design pathways are discussed.

Tetragonal Mn 3Àx Ga (0 x 1) epitaxial films possess exceptional magnetic and electronic properties. Stoichiometric Mn 3 Ga crystallizes in the D0 22 structure (abstract figure) and is a collinear ferrimagnet with an easy c-axis. It exhibits a unique combination of low magnetization, high uniaxial anisotropy, high Curie temperature and high spin polarization, which suit the requirements for spin torque memories down to 10 nm in size. Mn 2 Ga, on the other hand, exhibits much higher magnetization, high perpendicular anisotropy and high Curie temperature but a lower spin polarization, which make it a potential candidate for high density bit-patterned recording with areal densities up to 10 Tb inch À2 ($15 kb mm À2) and 10-year thermal stability. The flexibility of the D0 22 structure allows a variety of magnetic materials to be synthesized with varying x to suit specific magnetic applications. Hexagonal D0 19 -Mn 3 Ga films are antiferromagnetic, which could be useful for exchange bias.(a) The tetragonal D0 22 unit cell of Mn 3 Ga. Ga atoms are ordered in a body-centred tetragonal structure and Mn atoms occupy 2b (red) and 4d (green) sites. (b) The hexagonal D0 19 unit cell of Mn 3 Ga.

“…Note that this method is different from the magneticfield or spin-torque induced magnetization reversal, since in the latter two cases the magnetic properties can be regarded as unchanged in the process. Based on this idea, heat-assisted magnetic recording (HAMR) technology has been under rapid development in recent years, and is expected to increase the limit of magnetic recording dramatically [12,13]. However, the high density integration of the heating assemblies remains a great challenge, which involves attaching and aligning a semiconductor diode laser to the write head and implementing near-field optics to deliver the heat at nanoscale [13].…”

The responses of magnetic moments to external stimuli such as magnetic-field, heat, light, and electric-field have been utilized to manipulate the magnetism in magnetic semiconductors, with many of the novel ideas applied even to ferromagnetic metals. Here, we review a new experimental development on the control of magnetism in (Ga,Mn)As thin films by surface decoration of organic molecules: Molecules deposited on the surface of (Ga,Mn)As thin films are shown to be capable of significantly modulating their saturation magnetization and Curie temperature. These phenomena are shown to originate from the carrier-mediated ferromagnetism in (Ga,Mn)As and the surface molecules acting as acceptors or donors depending on their highest occupied molecular orbitals, resembling the charge transfer mechanism in a pn junction in which the equilibrium state is reached on the alignment of Fermi levels.
