Linear magnetoconductivity in magnetic metals
arXiv:2103.08503 · doi:10.1103/PhysRevB.104.L140407
Abstract
We theoretically describe a mechanism of low-field linear magnetoconductivity in helical magnetic metals. Two ingredients for the mechanism in three-dimensional metals are identified to be the spin-orbit coupling and momentum-dependent ferromagnetic exchange interaction. We propose and study a number of minimal theoretical models which have linear magnetoconductivity, and discuss their implications for recent experiments.
