Magnetic, thermal and transport properties of Tb3Ru4Al12.

Popis výsledku v původním jazyce

Tb3Ru4Al12 (hexagonal crystal structure) having a distorted kagome net of the Tb atoms is studied on a single crystal by measurements of magnetization, specific heat and electrical resistivity. The system is an antiferromagnet with the Neel temperature 22 K. A substantial magnetic anisotropy is observed that persists at least up to 60 T. Tb3Ru4Al12 displays field-induced magnetic phase transitions: one along [100] and [120] and two along the [001] axis. The transitions are accompanied by sharp peaks inmagnetoresistance and subsequently lead to a large negative effect in it, 20% in the longitudinal and 40% in the transverse geometry. The peaks are explained by changes in conduction electron spectra at the transitions due to the interaction between theconduction electrons and localized magnetic moments. The large negative effect suggests field-induced magnetic phases with a reduced period as compared to zero field.
