摘要
InSb samples containing 0.22-1.42 wt % manganese were synthesized and identified. The unit cell parameter decreased as the manganese concentration increased. The samples contained microinclusions of manganese antimonides. Electrical and magnetic measurements showed two ferromagnetic phases (In1-x MnxSb solid solution with T-c similar to 7 K and MnSb with T-c similar to 580 K) and a ferrimagnetic phase (Mn2Sb). The samples had p-type conductivity with a charge carrier concentration of about 10(20) cm(-3). The semiconductor conductivity was observed at low temperatures and changed to the metal conductivity with temperature elevation.
