Local inversion symmetry breaking and spin-phonon coupling in the perovskite GdCrO3

Mahana, S.; Rakshit, B.; Basu, R.; Dhara, S.; Joseph, B.; Manju, Unnikrishnan; Mahanti, S.D.; Topwal, D. (Physical Review B, 96(10), 2017)

Our detailed temperature-dependent synchrotron powder x-ray diffraction studies along with first-principles density-functional-theory-based calculations enable us to shed light on the origin of ferroelectricity in GdCrO3. ...
Probing the Electronic Structure of Hybrid Perovskites in the Orientationally Disordered Cubic Phase

Nandi, P.; Pandey, S.K.; Giri, C.; Singh, V.; Petaccia, L.; Manju, U.; Mahanti, S.D.; Topwal, D. (Journal of Physical Chemistry Letters, 11(14), 2020: 5719-5727)

Hybrid organic-inorganic lead halide perovskites are projected as new generation photovoltaic and optoelectronic materials with improved efficiencies. However, their electronic structure so far remains poorly understood, ...
Site substitution in GdMnO3: Effects on structural, electronic, and magnetic properties

Mahana, S.; Pandey, S.K.; Rakshit, B.; Nandi, P.; Basu, R.; Dhara, S.; Turchini, S.; Zema, N.; Manju, U.; Mahanti, S.D.; Topwal, D. (Physical Review B, 102(24), 2020: 245120)

We report on detailed structural, electronic, and magnetic studies of GdMn1-xCrxO3 for Cr doping levels; x = 0 <= x <= 1. X-ray diffraction studies suggest that GdMn0.5Cr0.5O3 has a monoclinic P2(1)/b structure with alternate ...
