Analytic Expression for Magnetic Activation Energy
Daisuke Miura, Akimasa Sakuma
We theoretically investigate the magnetic activation energy of permanent magnets. Practically, it is widely used in a phenomenological form as $\mathcal{F}_\mathrm{B}(H_\mathrm{ext…
Noncollinearity effects on magnetocrystalline anisotropy for FeB magnets
Daisuke Miura, Akimasa Sakuma
We present a theoretical investigation of the magnetocrystalline anisotropy (MA) in FeB ( is a rare-earth element) magnets in consideration of the non-collinearity e…
Tunable Spin Seebeck Diode with Magnonic Spin Tunneling Junction
Diasuke Miura, Akimasa Sakuma
We theoretically investigate the spin--wave spin current induced by the spin Seebeck effect in magnonic spin tunneling junctions (MSTJs) for arbitrary magnetization directions. We…
Anisotropy of exchange stiffness based on atomic-scale magnetic properties in rare-earth permanent magnet NdFeB
Yuta Toga, Masamichi Nishino, Seiji Miyashita +2
We examine the anisotropic properties of the exchange stiffness constant, , for rare-earth permanent magnet, NdFeB, by connecting analyses with two differen…
Power law analysis for temperature dependence of magnetocrystalline anisotropy constants of NdFeB magnets
Daisuke Miura, Akimasa Sakuma
Phenomenological analysis for the temperature dependence of the magnetocrystalline anisotropy (MA) in rare earth magnets is presented. We define phenomenological power laws applica…
