Half-integer Shapiro steps at the 0-pi crossover of a ferromagnetic Josephson junction.
We investigate the current-phase relation of S/F/S junctions near the crossover between the 0 and the pi ground states. We use Nb/CuNi/Nb junctions where this crossover is driven both by thickness and temperature. For a certain thickness a nonzero minimum of critical current is observed at the crossover temperature. We analyze this residual supercurrent by applying a high frequency excitation a...
متن کاملHalf-Integer Shapiro Steps at the 0- Crossover of a Ferromagnetic Josephson Junction
257005-1 We investigate the current-phase relation of S=F=S junctions near the crossover between the 0 and the ground states. We use Nb=CuNi=Nb junctions where this crossover is driven both by thickness and temperature. For a certain thickness a nonzero minimum of critical current is observed at the crossover temperature. We analyze this residual supercurrent by applying a high frequency excita...
متن کاملQuantum Tunneling in Half-Integer Spin Systems
Motivated by the experimental observations of resonant tunnelings in the systems with half-integer spin, such as V15 and Mn4, we study the mechanism of adiabatic change of the magnetization in systems with the time-reversal symmetry. Within the time-reversal symmetric models, effects of several types of perturbations are investigated. Although tunneling between the ground states is suppressed i...
متن کاملGauss hypergeometric function : reduction , ε - expansion for integer / half - integer parameters and Feynman diagrams
The Gauss hypergeometric functions 2 F 1 with arbitrary values of parameters are reduced to two functions with fixed values of parameters, which differ from the original ones by integers. It is shown that in the case of integer and/or half-integer values of parameters there are only three types of algebraically independent Gauss hyperge-ometric functions. The ε-expansion of functions of one of ...
متن کاملAll-Order ε-Expansion of Gauss Hypergeometric Functions with Integer and Half-Integer Values of Parameters
It is proved that the Laurent expansion of the following Gauss hypergeometric functions, are an arbitrary integer nonnegative numbers, a, b, c are an arbitrary numbers and ε is an arbitrary small parameters, are expressible in terms of the harmonic polylogarithms of Remiddi and Vermaseren with polynomial coefficients. An efficient algorithm for the calculation of the higher-order coefficients o...
