Perturbative calculations of quantum spin tunneling in effective spin systems with a transversal magnetic field and transversal anisotropy
We present a perturbative approach for the resonant tunnel splittings of an arbitrary effective single spin system. The Hamiltonian of such a system contains a uniaxial anisotropy, a transversal magnetic field and a second-order transversal anisotropy. Further, we investigate the influence of the tr...
