摘要

Precise angle-resolved magnetoresistance (ARM) measurements are applied to reveal the origin of symmetry lowering in electron transport and the emergence of a huge number of magnetic phases in the ground state of the antiferromagnelic metal HoB_(12) with fcc crystal structure. By analyzing the polar H-θ-ψ magnetic phase diagrams of this compound reconstructed from the experimental ARM data, we argue that nonequilibrium electron density oscillations (dynamic charge stripes) are responsible for the suppression of the indirect Ruderman-Kittel-Kasuya-Yosida exchange along the (110) directions between the nearest neighboring magnetic moments of Ho~(3+) ions in this strongly correlated electron system.
