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…

Lattice dynamics and magnetic exchange interactions in GeCo2O4, a spinel with S = 1/2 pyrochlore lattice

Prativa Pramanik, Sobhit Singh, Mouli Roy Chowdhury +6

GeCoO is a unique system in the family of cobalt spinels ACoO (A= Sn, Ti, Ru, Mn, Al, Zn, Fe, etc.) in which magnetic Co ions stabilize on the pyrochlore lattice ex…

On the derivation of the magnetocaloric properties in ferrimagnetic spinel Mn3O4

S. Thota, F. Guillou, V. Hardy +3

Large magnetocaloric effect has been observed in Mn3O4 around its ferrimagnetic transition at TN = 42.75 K. Field-induced isothermal entropy changes (\DeltaS) were derived from bot…
