The (Ln, A)MnO3 perovskite manganites [1-3] (where Ln represents trivalent rare-earth elements, and A stands for divalent alkaline-earth cations) are considered as potential candidates for magnetic refrigeration because they exhibit pronounced MCEs, low density, good chemical stability, low cost and nontoxicity. Therefore, there has been a great deal of attention paid recently to the MCE of perovskite...
In recent years, spin-orbit torques induced by charge current in heavy metal/magnetic structures have attracted wide attention among researchers. Since the experimental demonstration of spin-orbit torques due to the spin Hall effect (SHE) being able to manipulate the magnetization direction in an in-plane MTJ structure[1], it has been heavily explored for applications in memory and logic. It provides...
The extended modeling of the magnetic properties of grain oriented electrical steel is presented in this paper which is based on a set of standard and scaled-down Epstein frames and a proposed two-level weighted processing of Epstein data, including the mean magnetic path length, specific magnetization loss and exciting power. The effects of excitation frequency, strip angle, and ambient temperature...
Summary form only given. We theoretically study the spin waves in an aperioci antiferromagnetic(AF)/ nonmagnetic(NM) multilayer, where the AF layer and the NM layer are arranged in the k-component Fibonacci sequence. The dispersion relation of magnetostatic spin waves and the precession amplitude of the total magnetization are obtained. The multiformity in frequency spectra leads to the tunable spin...
