Room temperature reversible colossal volto-magnetic effect in all-oxide metallicmagnet/topotactic-phase-transition material heterostructures
Sourav Chowdhury, Supriyo Majumder, Rajan Mishra +6
Multiferroic materials have undergone extensive research in the past two decades in an effort to produce a sizable room-temperature magneto-electric (ME) effect in either exclusive…
Exchange bias in SmNiMnO/BaTiO ferromagnetic-diamagnetic heterostructure thin films
S. Majumder, S. Chowdhury, B. K. De +4
Exchange bias (EB) shifts are commonly reported for the ferromagnetic (FM)/antiferromagnetic (AFM) bilayer systems. While stoichiometric ordered SmNiMnO (SNMO) and BaTi…
Magnetic properties of disordered polycrystalline bulk SmNiMnO double perovskite
S. Majumder, M. Tripathi, P. Rajput +3
The structural, electronic and magnetic properties of anti-site disordered SmNiMnO double perovskite has been studied. RENiMnO (RE: rare-earth) ordered…
Existence of inter coupled structural, electronic and magnetic states in SmNiMnO double perovskite
S. Majumder, M. Tripathi, D. O. de Souza +6
Coupling between different interactions allows to control physical aspects in multifunctional materials by perturbing any of the degrees of freedom. Here, we aim to probe the corre…
Robust electronic and tunable magnetic states in SmNiMnO ferromagnetic insulator
Supriyo Majumder, Malvika Tripathi, I Píš +5
Ferromagnetic insulators (FM-Is) are the materials of interest for new generation quantum electronic applications. Here, we have investigated the physical observables depicting FM-…
Microscopic insights of magnetism in SmNiMnO double perovskite
Supriyo Majumder, Malvika Tripathi, H. E. Fischer +5
The functional characteristics of double perovskites with unique ferromagnetic-insulator ground state have been controversial due to the unavoidable presence of anti-site disorders…
Mapping the magnetic state as a function of anti-site disorder in SmNiMnO double perovskite thin films
S. Majumder, M. Tripathi, R. Raghunathan +7
The predictability of any characteristic functional aspect in a double perovskite system has always been compromised by its strong dependence over the inevitably present anti-site…
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…
Hydrogen sensing characteristics of perovskite based calcium doped BiFeO3 thin films
Arindam Bala, S. B. Majumder, Moumita Dewan +1
Perovskite oxide based thin film gas sensors have long been considered as potential alternatives to commonly investigated binary metal oxides based sensors. BiFeO3, which is a prot…
Electronic structure depiction of magnetic origin in BaTiO thin film: A combined experimental and first-principles based investigation
Supriyo Majumder, Pooja Basera, Malvika Tripathi +4
With the motive of unraveling the origin of native vacancy induced magnetization in ferroelectric perovskite oxide systems, here we explore the consequences of electronic structure…
Role of local short-scale correlations in the mechanism of negative magnetization
M. Tripathi, T. Chatterji, H. E. Fischer +4
We elaborate here why the antiferromagnetically ordered GdCrO responds in a diamagnetic way under certain conditions, by monitoring the evolution of the microscopic global and…
