| contents | In order to further investigate the magnetic state of the RAgAl series, the magnetization measurements on the TbAgAl compound from this series have been extended to higher fields of 12 Tesla in the temperature range 2K-300K. The electrical resistivity in the temperature range 2-300K has been measured up to fields of 9 Tesla. The field dependence of magnetization at low temperatures suggests an antiferromagnetic state undergoing a metamagnetic transition to a ferromagnetic state above the critical field. The observation of large coercivity (unlike other compounds in the RAgAl series) and non-saturation of magnetization indicates a disordered magnetic state having both ferromagnetic and antiferromagnetic exchange interaction. The presence of competing interactions leading to a disordered state is also supported by transport measurements and is attributed presumably to the layered structure of the compound. |
