Magnetism and superconductivity are competitive types of order in correlated electron systems. However, when a magnetic material is brought in contact with a superconducting material to build a conjunction, a coexistence region exists near the boundary that can modify the properties of the heterostructure in a qualitative way. A crucial role is played by spin singlet-triplet mixed superconducting states that are present in the interface regions. We discuss the implications that such states have for physical properties of hybrid structures containing superconducting and magnetic materials.
