Structural order parameter and itinerant electron magnetism in Cd2Re2O7
arXiv:cond-mat/0304582 · doi:10.1016/j.jmmm.2003.11.397
Abstract
We describe the low temperature behaviour of the magnetic susceptibility of Cd2Re2O7 in terms of a Landau theory of structural phase transitions. We calculate the zero temperature Pauli susceptibility using a tight-binding approach to reveal the mechanism of coupling between the structural order parameter and itinerant magnetism.
