Beschreibungen/Notizen

• The X-ray diffraction, magnetization and electrical conductivity measurements for Gd0.9A0.1CoO3-delta (A=Ba, Sr) have been made. The complicated magnetic behavior, including the paramagnetic-ferromagnetic-antiferromagnetic and paramagnetic-ferromagnetic transitions, was found for Ba- and Sr-doped samples. The gradual insulator-metal transitions were observed in a wide temperature range T=600-800 K. The complex magnetic and transport data could be explained on the basis of the structural phase separation.
