Switching magnetic spin-states using small magnetic fields in compositionally complex Sm(M7)O
R. K. Dokala, M. Geers, P. Nordblad +2
High-entropy perovskites (HEPs) offer a unique platform for exploring magnetic phenomena arising from extreme B-site chemical disorder. In Sm(M7)O, where there are 7 cations in…
Temperature Dependent Magnetic and Structural Properties of Al Substituted Nanostructured Ferrites with Large Coercive Fields
P. Maltoni, R. K. Dokala, P. Pramanik +12
We report a comprehensive study of the temperature-dependent structural, magnetic, vibrational, and dielectric properties of Al-substituted M-type hexaferrites SrFeAlO…
Spin-Reorientation Dynamics and Strong-Spin Phonon Coupling in Ce-substituted SmCrO
Shaona Das, Ravi Kiran Dokala, Subhash Thota
We report the influence of Ce substitution on the magnetic structures and phonon dynamics in SmCrO perovskites. Magnetic landscapes are spanned by long-range canted anti…
Giant-Magnetocaloric effect and phonon dynamics in (GdCe)CrO
Ravi Kiran Dokala, Shaona Das, Subhash Thota
We investigate the effect of Ce substitution on the magnetic ordering and phonon dynamics of the GdCrO orthorhombic perovskite. The Ce doped compound exhibits long-range…
Mean field magnetism and spin frustration in a double perovskite oxide with compositional complexity
Nandana Bhattacharya, Ravi Kiran Dokala, Sourav Chowdhury +9
The rise of high-entropy oxides as a major functional materials design principle in recent years has prompted us to investigate how compositional disorder affects long-range magnet…
