Abstract
Magnetism, transport and specific heat measurements have been performed to the hexagonal perovskite 20% Fe-substituted Sr6Co5O15 (that is Sr6(Co0.8Fe0.2)5O15) polycrystalline samples with quasi-one-dimensional structure. The system exhibits paramagnetism above 270 K, and with decreasing temperature, it undergoes two ferromagnetic phase transitions FM-I and FM-II at 220 K and 170 K, respectively, which correspondingly show two downward jumps on the resistivity curve of 0 T. The 20% Fe-substituting-induced changes in magnetic properties are discussed to be due to the changes in spin exchanges.
