Nickel thin films (100 nm) deposited on 128∘Y -cut: LiNbO 3 exhibits a well-defined, uniaxial, magnetic anisotropy after annealing at 325 °C. Simulating the magnetization of these films using a temperature-dependent Stoner–Wohlfarth (SW) model indicates that the films have a very narrow angular distribution of anisotropy axis orientations. Here, we report a direct measurement of the angular distribution of […]

The spin Hall magnetoresistance (SMR) of Pt/FeCoB bilayers with in-plane magnetocrystalline anisotropy was analysed with respect to a second order effect in the sensing current which acts, through the spin Hall effect in Pt, as a torque on the magnetization of the ferromagnetic layer and changes slightly its configuration. This leads to a small current […]
