Thermal expansion and the pressure influence on the Curie temperature and the superconducting transition temperature of the ferromagnetic superconductor

[Abstract] Thermal expansion of ferromagnetic superconductors is studied again. It is assumed that the superconducting gap of the majority spin conduction band has a line node. The volume differential of the transfer integral is variable. The pressure influence of the Curie temperature and of the superconducting transition temperature on ferromagnetic superconductors is also examined
