Unconventional superconductivity with spin-triplet Cooper pairing is reviewed based on the quasi-phenomenological Ginzburg-Landau theory.The superconductivity, in particular, mixed phase of coexistence ferromagnetizm and unconventional triggered by spontaneous magnetization.The stable whereas other superconducting phases that usually exist superconductors are either unstable, or, for particular values parameters theory, some these metastable at relatively low temperatures a quite narrow domain diagram.The transitions from normal to first order while transition ferromagnetic can be or second depending concrete substance.The pair crystal anisotropy relevant more precise outline diagram shape reduce degeneration ground states system but they do not drastically effect stability domains thermodynamic properties respective phases.
