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…
Optimized Analysis of the AC Magnetic Susceptibility Data in Several Spin-Glass Systems using the Vogel-Fulcher and Power Laws
Mouli Roy-Chowdhury, Mohindar S. Seehra, Subhash Thota
In spin-glasses (SG), the relaxation time () vs. data at the peak position in the temperature variation of the ac magnetic susceptibilities at different fr…
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…
Experimental and Computational Studies of the Optical Properties of CuAl1-xFexO2
Mina Aziziha, Saeed Akbarshahi, Suresh Pittala +7
Delafossites are promising candidates for photocatalysis applications because of their chemical stability and absorption in the solar region of the electromagnetic spectrum. For ex…
Optical Properties of Dilute CuAlFeO Delafossite Alloys
Mina Aziziha, S. Akbarshahi, S. Ghosh +6
For powder samples of CuAlFeO ( 0, 0.01, 0.05, and 0.1), measured optical properties are compared with model simulations and phonon spectra are compared with s…
Neutron Diffraction Evidence for Local Spin Canting, Weak Jahn-Teller Distortion, and Magnetic Compensation in TiMnCoO Spinel
P. Pramanik, D. C. Joshi, M. Reehuis +5
A systematic study using neutron diffraction and magnetic susceptibility are reported on Mn substituted ferrimagnetic inverse spinel TiMnCoO in the temperatur…
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…
Magnetocaloric effect and improved relative cooling power in (La0.7Sr0.3MnO3/SrRuO3) superlattices
Q. Zhang, S. Thota, F. Guillou +4
Magnetic properties of a series of (La0.7Sr0.3MnO3/SrRuO3) superlattices, where the SrRuO3 layer thickness is varying, are examined. A room-temperature magnetocaloric effect is obt…
Anisotropic magnetocaloric effect in all-ferromagnetic (La0.7Sr0.3MnO3/SrRuO3) superlattices
S. Thota, Q. Zhang, F. Guillou +5
We exploit the magnetic interlayer coupling in La0.7Sr0.3MnO3/SrRuO3 superlattices to realize a crossover between inverse and conventional magnetic entropy changes. Our data reveal…
