Diamagnetic susceptibility of spin-triplet ferromagnetic superconductors

We calculate the diamagnetic susceptibility in zero external magnetic field above the phase transition from ferromagnetic phase to phase of coexistence of ferromagnetic order and unconventional superconductivity. For this aim we use generalized Ginzburg–Landau free energy of unconventional ferromagn...

Description
Summary:We calculate the diamagnetic susceptibility in zero external magnetic field above the phase transition from ferromagnetic phase to phase of coexistence of ferromagnetic order and unconventional superconductivity. For this aim we use generalized Ginzburg–Landau free energy of unconventional ferromagnetic superconductor with spin–triplet electron pairing. A possible application of the result to some intermetallic compounds is briefly discussed.
