Suppression of indirect exchange and symmetry breaking in antiferromagnetic metal with dynamic charge stripes

Abstract

Precise angle-resolved magnetoresistance (ARM) measurements are applied to reveal the origin for the lowering of symmetry in electron transport and the emergence of a huge number of magnetic phases in the ground state of antiferromagnetic metal HoB12 with fcc crystal structure. By analyzing of the polar H-theta-phi magnetic phase diagrams of this compound reconstructed from the experimental ARM data we argue that non-equilibrium electron density oscillations (dynamic charge stripes) are responsible for the suppression of the indirect RKKY exchange along <110> directions between the nearest neighboring magnetic moments of Ho3+ ions in this strongly correlated electron system.
