Beyond lead halide perovskites: visible light photovoltaics with phase engineered bismuth-based oxide double-perovskites, Bi2MCrO6 (M = Fe, Mn)
N P Vikas, Ranjit K Pradhan, Somdutta Mukherjee +4
Lead poisoning and notorious ambient instability in lead-based halide perovskites pave the way for the exploration of alternative materials for affordable and efficient solar cell…
Room temperature multiferroism in polycrystalline thin films of gallium ferrite
Monali Mishra, Amritendu Roy, Ashish Garg +2
Sol-gel deposited (010) textured polycrystalline thin films of gallium ferrite (GaFeO3 or GFO) on n-Si(100) and Pt/Si(111) substrates are characterized for room temperature multife…
Room Temperature Nanoscale Ferroelectricity in Magnetoelectric GaFeO3 Epitaxial Thin Films
Somdutta Mukherjee, Amritendu Roy, Sushil Auluck +3
We demonstrate room temperature ferroelectricity in the epitaxial thin films of magnetoelectric GaFeO3. Piezo-force measurements show a 180o phase shift of piezoresponse upon switc…
Effect of Site-disorder, Off-stoichiometry and Epitaxial Strain on the Optical Properties of Magnetoelectric Gallium Ferrite
Amritendu Roy, Somdutta Mukherjee, Surajit Sarkar +4
We present a combined experimental-theoretical study demonstrating the role of site disorder, off-stoichiometry and strain on the optical behavior of magnetoelectric gallium ferrit…
Spin Glass-like Phase below ~ 210 K in Magnetoelectric Gallium Ferrite
Somdutta Mukherjee, Ashish Garg, Rajeev Gupta
In this letter we show the presence of a spin-glass like phase in single crystals of magnetoelectric gallium ferrite (GaFeO3) below ~210 K via temperature dependent ac and dc magne…
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…
