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.

  14. We would like to point out that the works [13] and [12] turned out to be incomplete. Work [13] misses (M·B)E term in the current, as the work only focused on the terms due to the chiral anomaly, while [12] misses (E·M)B and (E·B)M terms in the current.

  21. Phenomenological theory proposed in Ref. [4] to describe the experiment misses the (E·M)B term in the current. In this theory a new force, F=αM×E, where α is some constant, is added to the equations of motion of conduction fermions when there is a magnetization in the system. Then, according to [4], this phenomenology is limited to describing only (M·B)E and (E·B)M terms in the current, but cannot describe the (E·M)B term. Equation for the k̇ indeed can have extra terms which are due to the Berry curvature (for a review see Ref. [16]), and which we have used in this Letter.
