Analysis
This paper investigates the impact of Cerium (Ce) substitution on the magnetic and vibrational properties of Samarium Chromite (SmCrO3) perovskites. The study reveals how Ce substitution alters the magnetic structure, leading to a coexistence of antiferromagnetic and weak ferromagnetic states, enhanced coercive field, and exchange bias. The authors highlight the role of spin-phonon coupling and lattice distortions in these changes, suggesting potential for spintronic applications.
