Abstract: The discovery of high-Tc cuprates superconductors is the beginning of an era for studying superconductivity. In order to obtain superconductors with even higher superconducting transition temperature, people starts to widely search new superconducting materials with unconventional mechanism. Here, we will introduce some representative superconducting material families and their basic physical properties. Finally, we will also make a prospect for the future of exploring new unconventional superconductors.
