Title: Metamagnetism - its universality and ubiquity
Speaker: Bellave Shivaram, University of Virginia
Abstract:
The emergent universality in the nonlinear magnetic response of itinerant metamagnets will be reviewed. Recent experimental work on heavy fermions, oxides, and single molecule magnets will be presented[ “Metamagnetism”, E. Stryjewski and N. Giordano, Advances in Physics, 26,487, (1977).]. The appeal of the ‘single energy scale model’ developed in the context of these new measurements
