Structure, transport and magnetic properties in a new layered ferromagnetic perovskite cobalt oxide Sr(2-x)Pr(x)Co04

Journal Article


Abstract

  • Abstract

    In this work, we report our studies on the structures, transport, and magnetic properties in the two-dimensional layer structured perovskite compound Sr2xPrxCoO4. Structure refinement revealed that these compounds crystallized in K2NiF4-type structures with space group I4/mmm. The lattice parameters c decreased with Pr doping levels x. The Curie temperatures (Tc) are found to be 200 K for Sr1.5Pr0.5CoO4. The resistivities were found to increase with doping levels x. A large coercive field of about 1 T was found for the sample of x = 0.75.
