First-principles study of the anisotropic magneto-Peltier effect
MDR Open Deposited
We study theoretically the anisotropic magneto-Peltier effect, which was recently demonstrated experimen-tally. A first-principles-based Boltzmann transport approach including the spin-orbit interaction shows that Nihas a larger anisotropy of the Peltier coefficient (ΔΠ) than Fe, consistent with experiments. It is clarified thatspin-flip electron transitions due to the spin-orbit interaction are the key in the mechanism of the large anisotropicmagneto-Peltier effect. Using our method, we further predict several ferromagnetic metals with much larger ΔΠ than that of Ni.
