Unusual Magnetic Field and Temperature Dependence of the Metamagnetic Transition in UCu<sub>0.6</sub>Bi<sub>2</sub>

ORAL

Abstract

Uranium-based compounds are an active source of interest due to the wide variety of exotic states that they can host. UCu0.6Bi2 orders antiferromagnetically below TN ≈ 54 K. For T < TN, there is a first-order metamagnetic transition under the application of magnetic field. The temperature and field-orientation dependence of the transition have been mapped using magnetization and MHz susceptibility measurements in fields of up to 60 T and for temperatures down to 0.65 K. Unusually large hysteresis is observed at the transition under certain conditions; the possible origin of this and other features will be discussed.
