Hall Effect in the Antiferromagnetic State of Ho0.8Lu0.2B12

Detailed measurements of the Hall effect in the Ho0.8Lu0.2B12 antiferromagnetic compound (Neel temperature T-N = 5.75 K) in magnetic fields up to 80 kOe oriented in the (110) plane at temperatures of 1.9-6.6 K are performed. It is established with the contribution separation procedure that the anisotropic positive contribution, which is responsible for the double inversion of the sign of the Hall resistance, dominates in the antiferromagnetic state of Ho0.8Lu0.2B12 in fields of 30-50 kOe. A sharp decrease in the amplitude of the isotropic negative contribution at the transition to the antiferromagnetic phase is found. The nature of the detected anomalies in the antiferromagnetic metal with dynamic charge stripes and spin-wave component of the magnetic structure is discussed.

Automated summary

Detailed measurements of the Hall effect in the antiferromagnetic compound Ho0.8Lu0.2B12 were performed in magnetic fields up to 80 kOe. The dominant contribution to the Hall resistance, which results in the double inversion of its sign, was found to be the anisotropic positive contribution. Additionally, a sharp decrease in the amplitude of the isotropic negative contribution at the transition to the antiferromagnetic phase was observed. The anomalies detected in this antiferromagnetic metal with dynamic charge stripes and spin-wave component of the magnetic structure are discussed.
