Superconductors are differentiated by there magnetization curves by two types. They are TYPE I and TYPE II Super conductor.
In Pure Material or TYPE I Superconductor, the specimen cannot resist the magnetic field from critical applied field HC. After HC magnetic field penetrate the specimen totally. It losses its super conducting properties completely.
In TYPE II superconductor usually alloys or composite, when the applied field crosses HC1 the specimen starts to loss its super conductivity. But field cannot penetrate fully and super conducting property is retained in the part of the specimen up to HC2. This region is called vortex state. After HC2 the specimen is in normal state.
