Description

The interplay between superconductivity and magnetism is outlined. The elements and phenomena related to these magnetic superconductors are introduced. The rare earth ternary superconductors, re-entrant superconductors, the weak-itinerant ferromagnetic superconductors Y9Co7 anomalies of Hc2 are discussed. The generalisation of Ginzburg-Landau theory and Abrikosov-Gorkov theory are presented. The superconducting and magnetic orders in heavy fermion compounds are surveyed and models are presented. The magnetism in La-214, Y-123, Bi-based and Tl-based high Tc cuprates and effect of pressure are surveyed and Heisenberg-Hubbard Hamiltonian, Chakravarthy-Halperin-Nelson theory, Dyaloshinksy-Moriya interaction, RVB model, Anyon model and Spin bag model are outlined.
