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…
The Linear and Non-linear Magnetic Response of a Tri-Uranium Single Molecule Magnet
B. S. Shivaram, Eric Colineau, Jean-Christophe Griveau +2
We report here low temperature magnetization isotherms for the single molecule magnet, . By analyzing the low temperature magnetization in terms of …
The CeMIn5 (M = Rh, Ir and Co) System and the Single Energy Scale Model of Metamagnetism
A. Thamizhavel, B. D. White, M. B. Maple +5
For a decade and a half, CeCoIn and related alloys have served as a rich playground to explore the interplay between magnetism and unconventional superconductivity. Despite thi…
High Field Ultrasound Measurements in UPt3 and the Single Energy Scale Model of Metamagnetism
B. S. Shivaram, V. W. Ulrich, Pradeep Kumar +1
We report longitudinal ultrasound velocity measurements for magnetic fields up to 33 T applied parallel to the a-axis of the heavy electron compound UPt. A characteristic dip…
Resonant Processes and Exciton Propagation in a Frozen Gas
J. S. Frasier, V. Celli
We present numerical simulations of a theory of resonant processes in a frozen gas of excited atoms interacting via dipole-dipole potentials that vary as , where is the…
Multiple energy x-ray holography: the polarization effect
V. Bortolani, V. Celli, A. M. Marvin
We present the theory for Multiple Energy X-ray Holography (MEXH), using a multipole expansion for the scattered field. We find that light polarization plays a crucial role in the…
