Abstract Recent increased development interest in millimeter-wave oscillator devices has necessitated realization of small oscillators with high frequency, wide frequency tunability, and room-temperature operation. Spin-torque oscillators (STOs) are

In this study, we numerically investigate the spin transfer torque oscillation (STO) in a magnetic orthogonal configuration by introducing a strong biquadratic magnetic coupling. The orthogonal configuration consists of top and bottom layers with in-

We numerically demonstrated the spin transfer torque oscillation (STO) in a magnetic orthogonal configuration by introducing a 90° magnetic coupling. In our model, the multilayer consists of a top layer with in-plane magnetic anisotropy, a nonmagnet

Exchange-coupled composite (ECC) media present a possible layered structure for microwave-assisted magnetic recording (MAMR) systems. In this paper, MAMR writability and read/write characteristics were computed using a micromagnetic simulation, which

Microwave-assisted magnetization switching (MAS) processes for granular films were demonstrated by time integration of the Landau–Lifshitz–Gilbert equation. At low microwave frequencies, hysteresis loops become narrower, and at higher frequencies

We fabricated quasiantiferromagnetic (quasi-AFM) layers with alternating antiparallel magnetization in the neighboring domains via 90° magnetic coupling through an Fe-O layer. We investigated the magnetic properties and the relationship between the

We investigated the relationship between the magnetic hysteresis loop and domain structure modulation of an artificial material, a quasi-antiferromagnet (AFM) with domains of alternating antiparallel magnetization fabricated by a strong 90° magnetic
