Macroscopic quantum tunneling and coherence of spins [PDF]
Solomon Akaraka OwerreWe present a review of suppression of tunneling rate (energy splitting) for half-odd-integer spins in ferromagnetic and antiferromagnetic particles. We also review the quenching of the tunneling rate in the presence of a magnetic field.View original: http://arxiv.org/abs/1212.4904
