Abstract / Description:The structure, magnetization, and electrical transport of
perovskite cobaltites La0.7Sr0.3Co1-yNiyO3 have been studied.
It is found that the substitution of Ni for Co induces no
apparent changes in bond length and angle in the Co(Ni)-O
network, and only moderately suppresses the ferromagnetism.
Moreover, a retention of the metallic conduction has been
observed from y=0 to 0.2, which is in strong contrast to the
reported insulating state of the other Co site doped
La0.7Sr0.3CoO3. A double-exchange-like interaction between Ni
ion and its neighboring Co ion is suggested to explain the
experimental results. (C) 2002 American Institute of Physics.
