摘要：
Single crystals of FeIn1-xCr2xS4 compounds have been grown by using the chemical transport method. DC magnetization measurements on single crystals for 0.6 <= x <= 1.0 revealed a reentrant behavior below T-sg = 120-170K depending on the Cr concentration sample. The transition temperature T-c increases as the indium concentration increases. The electrical resistivity measurements on polycrystalline materials above the Curie temperature revealed that the conduction behavior could be described as magnetic-polaron transport.
