Torque magnetometry studies of new low temperature metamagnetic states in ErNi2B2C Conference Paper uri icon

abstract

  • The metamagnetic transitions in single-crystal Er Ni2 B2 C have been studied at 1.9 K with a Quantum Design torque magnetometer. The critical fields of the transitions depend crucially on the angle between applied field and the easy axis [100]. Torque measurements have been made while changing the angular direction of the magnetic field (parallel to basal tetragonal ab planes) in a wide angular range (more than two quadrants). Sequences of metamagnetic transitions with increasing field are found to be different for the magnetic field along (or close enough to) the easy [100] axis from that near the hard [110] axis. The study have revealed new metamagnetic states in Er Ni2 B2 C, which were not apparent in previous longitudinal-magnetization and neutron studies. © 2008 American Institute of Physics.
