Abstract

In pulsed magnetic fields up to 65T and at temperatures below the Neel transition, our magnetization and magnetostriction measurements reveal a field-induced metamagnetic-like transition that is suggestive of an antiferromagnetic to polarized paramagnetic or ferrimagnetic ordering. Our data also suggests a change in the nature of this metamagnetic-like transition from second- to first-order-like near a tricritical point at Ttc 145K and Hc52T. At high fields for H>Hc we found a decreased magnetic moment roughly half of the moment reported in low field measurements. We propose that f-p hybridization effects and magnetoelastic interactions drive the decreased moment, lack of saturation at high fields, and the decreased phase boundary.
