Emergent room-temperature ferroelectricity in spark-plasma sintered DyCrO and LaCrO
Suryakanta Mishra, Keerthana, Krishna Rudrapal +6
Identification of novel multiferroic materials with high-ordering temperatures remains at the forefront of condensed matter physics research. In this regard, the antiferromagnetic…
Engineering room-temperature multiferroicity in Bi and Fe codoped BaTiO3
Pratap Pal, Tapas Paramanik, Krishna Rudrapal +8
Fe doping into BaTiO3, stabilizes the paraelectric hexagonal phase in place of the ferroelectric tetragonal one [P. Pal et al. Phys. Rev. B, 101, 064409 (2020)]. We show that simul…
Origin and tuning of room-temperature multiferroicity in Fe doped BaTiO
Pratap Pal, Krishna Rudrapal, Sudipta Mahana +5
Simultaneous co-existence of room-temperature(T) ferromagnetism and ferroelectricity in Fe doped BaTiO (BTO) is intriguing, as such Fe doping into tetragonal BTO, a room-T ferr…
Emergent antiferromagnetism of YTiO3 in YTiO3-CaTiO3 superlattices
P. Pal, X. Liu, M. Kareev +2
Transport and magnetoresistance measurements are performed on metallic, high-carrier density YTiO3-CaTiO3 superlattices as a probe towards the investigation of an emergent magnetic…
Magnetization in electron- and Mn- doped SrTiO3
D. Choudhury, B. Pal, A. Sharma +2
Mn-doped SrTiO_3.0, when synthesized free of impurities, is a paramagnetic insulator with interesting dielectric properties. Since delocalized charge carriers are known to promote…
XPS evidence for molecular charge-transfer doping of graphene
D. Choudhury, B. Das, D. D. Sarma +1
By employing x-ray photoelectron spectroscopy (XPS), we have been able to establish the occurrence of charge-transfer doping in few-layer graphene covered with electron acceptor (T…
Near room-temperature colossal magnetodielectricity and multiglass properties in partially-disordered La2NiMnO6
D. Choudhury, P. Mandal, R. Mathieu +8
We report magnetic, dielectric and magnetodielectric responses of pure monoclinic bulk phase of partially-disordered La2NiMnO6, exhibiting a spectrum of unusual properties and esta…
Tuning of dielectric properties and magnetism of SrTiO3 by site-specific doping of Mn
D. Choudhury, S. Mukherjee, P. Mandal +12
Combining experiments with first principles calculations, we show that site-specific doping of Mn into SrTiO3 has a decisive influence on the dielectric properties of these doped s…
Electric and magnetic polarizabilities of hexagonal Ln2CuTiO6 (Ln=Y, Dy, Ho, Er and Yb)
Debraj Choudhury, Abhijit Hazarika, Adyam Venimadhav +9
We investigated the rare-earth transition metal oxide series, Ln2CuTiO6 (Ln=Y, Dy, Ho, Er and Yb), crystallizing in the hexagonal structure with non-centrosymmetric P63cm space gro…
