Static and dynamic magnetic properties of circular and square cobalt nanodots in hexagonal cells

“…19,21 On the other hand, the study of the dynamic properties of magnetic nanostructures has received increasing attention, offering emerging applications in spintronics-based devices such as magnetic random-access memories (MRAMs) for microwave signal processing, [22][23][24] spin-torque nano-oscillator (STNO) 23,25,26 and spin-current nano-oscillators (SCNO). 27,28 In this sense, a recent report on the study of SCNO devices by means of micromagnetic simulations shows the feasibility in the development of sensitive frequency-based nano-biosensors for detecting single magnetic nanostructures. 29 Besides, the demand for high-frequency communications in various civil and military applications represents great opportunities in the field of microwave technology because magnetic materials are known for their use in passive microwave devices over a wide frequency range from the sub-GHz to sub-THz range.…”

Thickness-dependent magnetic properties in Pt/[Co/Ni] n multilayers with perpendicular magnetic anisotropy

“…[12][13][14][15][16][17] Among these PMA multilay-ers, the PMA [Co/Ni] multilayer also exhibits low damping constant, [14] which gets much attention, especially for the fields of current-driven auto-oscillation of magnetization and excitation and manipulation of spin-waves. [18,19] Furthermore, the PMA [Co/Ni] multilayer is also useful for spin-orbit torque devices. [20][21][22] Therefore, [Co/Ni] multilayers are considered one of the most promising PMA ferromagnets in various spintronic devices.…”
