ArXiv

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.

ArXiv

Analysis

This paper investigates the effect of Cerium (Ce) doping on the magnetic and phonon properties of Gadolinium Chromite (GdCrO3). The key finding is a significant enhancement of the magnetocaloric effect, making the material potentially useful for magnetic refrigeration. The study explores the interplay between spin-orbit coupling, spin-phonon coupling, and magnetic ordering, providing insights into the underlying physics.
