"The Linear and Nonlinear Magnetic Response in Strongly Correlated Metals"
I will describe two phenomena from the world of heavy fermion physics - one very specific and one that appears general enough to apply to all strongly correlated metals. The metal URu2Si2 exhibits a magnetic transition whose order parameter has so far been "hidden". I will describe sensitive magnetization measurements that throw light on the special nature of this hidden order in this unique metal. The more general phenomenon pertains to our observations in UPt3 that appear to establish a universal rule for the behavior of the equilibrium nonlinear susceptibility in all strongly correlated electronic systems.
