Abstract
We report the structural and magnetic characterization carried out on three non-stochiometric phases of oxygen deficient SrFeO3-δ samples close to the cubic, tetragonal and orthorhombic structures with oxygen composition of 2.97, 2.86 and 2.73 respectively. A Strong magnetic irreversibility is observed for the tetragonal and orthorhombic phases up to 230 K. Temperature dependence of electron spin resonance measurements on these samples are investigated. © 2010 American Institute of Physics.
