The NMR measurements performed on a single orthorhombic crystal of superconducting ferromagnet UCoGe (Y.Ihara et al, Phys. Rev. Lett. v.105, 206403 (2010)) demonstrate strongly anisotropic magnetic properties this material. presented calculations allow to establish the dependence longitudinal spin-lattice relaxation rate from temperature and field. value 1/T_1T in field perpendicular spontaneou...

A second order relativistic hydrodynamic theory has been derived using momentum dependent relaxation time in the transport equation. In to do that an iterative technique of gradient expansion approach, namely Chapman-Enskog (CE) particle distribution function employed. The key findings this work are (i) collision term results extended Landau matching condition for thermodynamic variables, (ii) ...
