Polymorphism in Cu-substituted GaV4S8: structural and electronic properties

The hexagonal and cubic phases of Ga1−xCuxV4S8 are obtained by different methods of preparation. The reaction of elements above 900°C gives hexagonal phases for large range of x=0.02–0.5. These are metallic and show enhanced paramagnetism. The reduction of oxides by H2S at a lower temperature of 700...
