An Effective Spin Hamiltonian Approach to Metamagnetism - I
P. Kumar, B. S. Shivaram, V. Celli
We describe a minimal model, based on a spin only Hamiltonian with a single energy scale for itinerant electron metamagnetism. Within this model the metamagnetic critical field is…

Universality in the Magnetic Response of Metamagnetic Metals
B. S. Shivaram, D. G. Hinks, M. B. Maple +2
We report in this paper, measurements of the nonlinear susceptibility χ_sub3(T) in the metamagnetic heavy fermion (HF) compound UPt3. At high temperatures, χ_sub3(T) < 0 and small.…
