Quantum tunneling of the magnetization in the thermally activated regime has been studied on Fe-8 single crystals by frequency dependent specific heat measurements as a function of applied magnetic field. Curves are very well described by a microscopic theory based on phonon assisted spin tunneling. However, an additional peak appears that can be due to transitions in higher multiplets

Abstract

Quantum tunneling of the magnetization in the thermally activated regime has been studied on Fe-8 single crystals by frequency dependent specific heat measurements as a function of applied magnetic field. Curves are very well described by a microscopic theory based on phonon assisted spin tunneling. However, an additional peak appears that can be due to transitions in higher multiplets
