Non-equilibrium spin dynamics in the temperature and magnetic field dependence of magnetization curves of ferrimagnetic CoFeO and its composite with BaTiO
R. N. Bhowmik, R. Ranganathan
A comparative study of the non-equilibrium magnetic phenomena (magnetic blocking, memory, exchange bias and aging effect) has been presented for ferrimagnetic CoFe$_{1.25}…
Effect of annealing temperatures on the electrical conductivity and dielectric properties of Ni1.5Fe1.5O4 spinel ferrite prepared by chemical reaction at different pH values
K. S. Aneesh Kumar, R. N. Bhowmik
The electrical conductivity and dielectric properties of Ni1.5Fe1.5O4 ferrite has been controlled by varying the annealing temperature of the chemical routed samples. The frequency…
Evidence of room temperature magnetoelectric properties in α-Fe1.6Ga0.4O3 oxide by magnetic field controlled electric properties and electric field controlled magnetism
