Spin–orbit torque (SOT) in the heavy elements with a large spin–orbit coupling (SOC) has been frequently used to manipulate magnetic states spintronic devices. Recent theoretical works have predicted that surface oxidized light negligible SOC can yield sizable orbit (OT), which plays an important role switching magnetization. Here, we report anomalous-Hall-resistance and harmonic-Hall-voltage measurements on perpendicularly magnetized Ta/Cu/[Ni/Co]5/Cu-CuOx multilayers. Both efficiency...

The Dzyaloshinskii–Moriya interactions (DMI) naturally breaking spatial inversion symmetry are considered a key factor in realizing current-induced magnetization switching by spin–orbit torque (SOT) without an in-plane assistance field. Ferrimagnets (FIM) composed of rare earth and transition metals show peculiar properties near the magnetic compensation point, including exceptionally high SOT efficiency significantly enhanced DMI effective Here, we investigate FIM [Co/Gd]N multilayers with...

The manipulation of Néel vector antiferromagnetic (AFM) layer by an applied stress has attracted considerable attention due to the technical importance for AFM-based spintronic devices. Here, we fabricated CoFeB/IrMn and Ni/IrMn exchange bias (EB) bilayers on PMN-PT(011) quantitatively study AFM magnetostrictive behaviors IrMn layer. Numerical calculations based Stoner–Wohlfarth model show that response compressive can be detected measuring angular dependent EB. hysteresis loops...

Surface plasmons are electromagnetic modes bounded at the metal-dielectric interfaces, which have numerous applications due to strong field enhancement effect. Therefore, controlling surface is in high demand for modern photonics and plasmonics. In this Letter, we propose a kind of metasurface launching with controlled phase based on Babinet principle. The control achieved by arranging C-shaped apertures metal that exhibits highly efficient electric dipole resonance. By properly designing...

The anti-trigonometric function is used to strictly solve the uniaxial anisotropic Stoner–Wohlfarth (SW) model, which can obtain relation of angle α ( θ ) between magnetization (the anisotropy field) and applied magnetic field. Using this analytic solution, hysteresis loops SW particles magnetized in typical directions could be numerically calculated. Then, are obtained randomly distributed particle ensembles while ignoring dipole interaction among them with solution. Finally, correctness...
