Spin-current model of electric polarization with the tensor gyromagnetic ratio
Mariya Iv. Trukhanova, Pavel A. Andreev
The spin-current model of electric polarization of spin origin is developed for a magnetic structure with anisotropic tensor gyromagnetic ratio (g-factor). Three mechanisms of the…

Spin waves and instabilities in the collinear four component antiferromagnetic materials
Pavel A. Andreev
The small amplitude perturbations of spins are considered in the four component antiferromagnetic materials with the equilibrium state of form up-up-down-down (uniaxial samples). O…
