Spin-reorientation transition and exchange-bias effect in CeFe0.5Cr0.5O3 ceramics
The polycrystalline CeFe0.5Cr0.5O3 ceramics were synthesized by the solid-state method, whose structural and magnetic properties were systematically studied. With the interaction between Ce and Fe/Cr ions, a first-order spin-reorientation transition from Γ4 to Γ1 is observed over a wide temperature interval in CeFe0.5Cr0.5O3, which is remarkably sensitive to applied magnetic field. Interestingly, the exchange-bias effect is found in CeFe0.5Cr0.5O3 ceramics during the spin-reorientation transition, ascribed to the paramagnetic/antiferromagnetic system presented by the two interacting magnetic sublattices (Ce and Fe/Cr). The coexistence of spin-reorientation transition and exchange-bias effect is promising to expand the practical application of CeFe0.5Cr0.5O3 ceramics in multifunctional spintronics.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
