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…
Magnetic glassy state at low spin state of Co3+ in EuBaCo2O5+δ (δ = 0.47) cobaltite
Archana Kumari, C. Dhanasekhar, Praveen Chaddah +6
The magnetic glassy state is a fascinating phenomenon, which results from the kinetic arrest of the first order magnetic phase transition. Interesting properties, such as metastabl…
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…
Electron doping induced magnetic glassy state in phase separated YBaCoO
Archana Kumari, C. Dhanasekhar, A. K. Das
The structural, magnetic and transport properties of the layered RBaCoO cobaltites are sensitive to the oxygen stoichiometry. In this present study, we report the prese…
Terahertz frequency magnetoelectric effect in Ni doped CaBaCoO
Shukai Yu, C. Dhanasekhar, Venimadhav Adyam +8
We present a study of terahertz frequency magnetoelectric effect in ferrimagnetic pyroelectric CaBaCoO and its Ni-doped variants. The terahertz absorption spectrum of these…
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…
