Abstract
Magnetic properties of frustrated antiferromagnet TbAuIn are investigated by AC susceptibility, resistivity as well as specific heat measurements. In temperature dependence of the susceptibility two anomalies are visible, one at 33Â K and another at 48Â K. According to neutron diffraction studies the Néel temperature is 35Â K. The second anomaly in the AC susceptibility seems to be attributed to antiferromagnetic cluster-glass state of Tb magnetic moments. The resistivity measurements confirm that TbAuIn exhibits long-range magnetic order below 35Â K, moreover they reveal an anomalous behaviour above that temperature. However in the temperature dependence of the specific heat only one anomaly at 30Â K is visible. The low temperature behaviour of susceptibility, resistivity and specific heat of the investigated antiferromagnetic material can be described, with a good accuracy, within the spin-wave theory with linear dispersion relation.
