Giant exchange bias in antiferromagnetic Pr<sub>2</sub>CoFe<sub>0.5</sub>Mn<sub>0.5</sub>O<sub>6</sub>: a structural and magnetic properties study
Abstract
<jats:title>Abstract</jats:title><jats:p>Antiferromagnetic (AFM) materials with a colossal exchange bias (EB) effect find applications as high-density spintronic devices. We report structural (geometrical and electronic) and magnetic studies in the polycrystalline Pr<jats:sub>2</jats:sub>CoFe<jats:sub>0.5</jats:sub>Mn<jats:sub>0.5</jats:sub>O<jats:sub>6</jats:sub> double perovskite system. The observed lack of training effect suggests the existence of robust EB. In addition, the detailed magnetic studies and Raman studies unravel the Griffith-like phase along with the spin-phonon coupling in the present system. The x-ray photoemission spectroscopy (XPS) analysis supports more than one valence state of B-site elements, which is accountable for the competition between ferromagnetic (FM) and AFM interactions in addition to the anti-site disorder in the system. The neutron measurement confirms the G-type AFM spin arrangement, accredited by the DFT calculation. The magnetic studies have correlated with the electronic structure, neutron study, and theoretical first principle calculations.</jats:p>
