Anisotropic Magnetostriction Measurements in UPt3 to 65 T

ORAL

Abstract

We present magnetostriction measurements obtained in pulsed magnetic fields upto 65 T at the NHMFL/Los Alamos in single crystals of UPt3 for field both parallel and perpendicular to the c-axis. While we reproduce published results at low fields the measurements at the highest fields for field parallel to the basal plane reveal a surprising downward trend in the magnetostriction. All these observations will be examined in the context of the single energy scale model of metamagnetism in heavy electron materials.
