First- and second-order crossover between quantum and classical regimes for the escape rate of a nanomagnet manipulated by a Josephson current
Employing the instanton technique and the nonlinear perturbation method, we study quantum-classical escape rate crossover for several forms of magnetic anisotropy in a nanomagnet sandwiched between two superconductors called Josephson φ0 junction. It is shown that the phase boundary separating the f...
