Escape rate of the nanospin system in a magnetic field: the first-order phase transition within quantum regime

Chang Soo Park, Sahng-Kyoon Yoo, D. K. Park +1

We have investigated the escape rate of the nanospin particle with a magnetic field applied along the easy axis. The model studied here is described by the Hamiltonian $\hat{\cal H…
