First Principle Study of Magnetism and Magneto-structural Coupling in Gallium Ferrite
Amritendu Roy, Rajendra Prasad, Sushil Auluck +1
We report a first-principles study of the magnetic properties, site disorder and magneto-structural coupling in multiferroic gallium ferrite (GFO) using local spin density approxim…
Composition Dependence of Structural Parameters and Properties of Gallium Ferrite
Somdutta Mukherjee, Vishal Ranjan, Rajeev Gupta +1
We show the effect of composition on structural and magnetic characteristics of pure phase polycrystalline Ga<2-x>Fe<x>O<3> (GFO) for compositions between 0.8 <= x <= 1.3. X-ray an…
Probing Magnetoelastic Coupling and Structural Changes in Magnetoelectric Gallium Ferrite
Somdutta Mukherjee, Rajeev Gupta, Ashish Garg
Temperature dependent X-ray diffraction and Raman spectroscopic studies were carried out on the flux grown single crystals of gallium ferrite with Ga:Fe ratio of 0.9:1.1. Site occu…
Electronic Structures, Born Effective Charges and Spontaneous Polarization in Magnetoelectric Gallium Ferrite
Amritendu Roy, Somdutta Mukherjee, Rajeev Gupta +3
We present a theoretical study of the structure-property correlation in gallium ferrite, based on the first principles calculations followed by a subsequent comparison with the exp…
