Thermal expansion and magnetostriction of the heavy fermion antiferromagnet YbAgGe

ORAL

Abstract

YbAgGe is a stoichiometric heavy fermion antiferromagnet that exhibits field induced quantum criticality.~ We will discuss new thermal expansion and magnetostriction measurements that clarify aspects of the quantum criticality and phase diagram of this model system.
