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…
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…
Low field magnetoelectric effect in Fe substituted Co4Nb2O9
C. Dhanasekhar, S. K. Mishra, R. Rawat +2
Co4Nb2O9 (CNO) having α-Al2O3 crystal structure with Co chains along c-direction shows gigantic magnetoelelctric coupling below antiferromagnetic ordering temperature of 27 K but a…
