Pt/Co/heavy metal (HM) tri-layered structures with interfacial perpendicular magnetic anisotropy (PMA) are currently under intensive research for several emerging spintronic effects, such as spin-orbit torque (SOT) [1, 2], domain wall motion [3, 4] and room temperature skyrmions [5, 6].
Finemet-type nanocrystalline soft magnetic alloys have shown attractive magnetic properties[1-3]. However, due to the relatively low Curie point of the residual amorphous matrix, they cannot be used at high temperature[4-5]. Partial substitution of Co for Fe was carried out to meet the desire for high temperature magnetic properties[6-7]. When Co was added to the FeSiBNbCu alloys, although the Curie...
Soft magnetic alloys have been widely applied to modern technology devices, such as transformer cores, choke coils and inductive devices. Magnetic field annealing can induce an uniaxial magnetic anisotropy Ku [1-4] so as to improve the soft magnetic properties of alloys for the purpose of coping with different application requirements. So far, FeCo-based nanocrystalline alloys have been explored increasingly...
Finemet alloys exhibit superior soft magnetic properties with high initial permeability (μ), low coercivity and low core loss, which attracted a great deal of attention [1]. However, their application is limited to the temperature close to the Curie point of an amorphous matrix, Tcam, because the intergranular magnetic coupling is usually interrupted by the paramagnetic amorphous matrix. As the result,...
