Spin-orbit-coupled superconductivity
Superconductivity and spin-orbit (SO) interaction have been two separate emerging fields until very recently that the correlation between them seemed to be observed. However, previous experiments concerning SO coupling are performed far beyond the superconducting state and thus a direct demonstration of how SO coupling affects superconductivity remains elusive. Here we investigate the SO coupli...
متن کاملSuperconductivity and Spin Fluctuations
The organizers of the Memorial Session for Herman Rietschel asked that I review some of the history of the interplay of superconductivity and spin fluctuations. Initially, Berk and Schrieffer showed how paramagnon spin fluctuations could suppress superconductivity in nearly-ferromagnetic materials. Following this, Rietschel and various co-workers wrote a number of papers in which they investiga...
متن کاملSuperconductivity and spin-glass like behavior in system with Pd sheet sandwiched between graphene sheets
Pd-metal graphite (Pd-MG) has a layered structure, where each Pd sheet is sandwiched between adjacent graphene sheets. DC magnetization and AC magnetic susceptibility of Pd-MG have been measured using a SQUID magnetometer. Pd-MG undergoes a superconducting transition at Tc (= 3.63±0.04 K). The superconductivity occurs in Pd sheets. The relaxation of MZFC (aging), which is common to spin glass s...
متن کاملChiral spin states and superconductivity.
It is shown that several different order parameters can be used to characterize a type of P and T -violating state for spin systems, that we call chiral spin states. There is a closely related, precise notion of chiral spin liquid states. We construct soluble models, based on P and T symmetric local spin Hamiltonians, with chiral spin ground states. Mean field theories leading to chiral spin li...
متن کاملXY Spin Glass
The chiral glass behaviour of the nearest-neighbour random-bond XY spin glass in four dimensions is studied by Monte Carlo simulations. A chiral glass transition at T cg = 0.90 ± 0.05 is found by a finite-size scaling analysis of the results. The associated chiral correlation-length exponent is estimated to be ν cg = 0.6 ± 0.1 and η cg ∼ 0.25. The values for the chiral critical temperature and ...
