Coexistence of magnetic and dielectric glassy states in alternating kagome and triangular lattice LuBaCoO cobaltite
C. Dhanasekhar, D. Chandrasekhar Kakarla, Archana kumari +10
To date, the alternating kagome and triangular lattice cobaltites, RBaCoO (R = Ca, Y, and rare earth elements), have been well studied for their large structural distortion…
Magnetic Structure and dielectric properties of antiferromagnetic FeCrO3
Rajesh kumar R, C. Dhanasekhar, N. Vijay Prakash Chaudhary +2
We report the enhancement of Néel temperature of Cr2O3 by replacing 50% of Cr by Fe prepared by sol-gel method. The structural analysis by neutron diffraction has revealed that FeC…
Structural, magnetic and electric polarization properties of geometrically frustrated YBaCo4O7 and DyBaCo4O7 cobaltites
C. Dhanasekhar, A. K Das, A. Das +3
In RBaCo4O7 (R = Ca, Y and Rare earth) cobaltite family, only CaBaCo4O7 shows 3D long range ferrimagnetic and spin driven electric polarization properties. In the present study, we…
Defect induced polarization and dielectic relaxation in GaFeO
Sudipta Mahana, C. Dhanasekhar, A. Venimadhav +1
We report results of the dielectric and pyroelectric measurements on solid solutions of GaFeO with x = 0.75, 1.0 and 1.25. These systems exhibit dipolar cluster…
Switching from pyroelectric to ferroelectric order in Ni doped CaBaCo4O7
C. Dhanasekhar, A. K Das, Ripandeep Singh +4
We report ferroelectric ordering in Ni substituted CaBaCo4O7. Magnetization showed ferrimagnetic transition at 60 K and an additional transition is found ~ 82 K, further, enhanced…
Absence of dipolar ordering in Co doped CuO
N Vijay Prakash Chaudhary, J. Krishna Murthy, A. Venimadhav
Polycrystalline CuO samples with Co doping were prepared by solid state method with flowing oxygen condition and examined their structural and multiferroic properties. Structural s…
