Feedback Effect on Landau-Zener-Stueckelberg Transitions in Magnetic Systems

Abstract

We examine the effect of the dynamics of the internal magnetic field on the staircase magnetization curves observed in large-spin molecular magnets. We show that the size of the magnetization steps depends sensitively on the intermolecular interactions, even if these are very small compared to the intra-molecular couplings.
