Enhanced negative capacitance in La-doped Pb(ZrTi)O ferroelectric capacitor from tuning of bias voltage pulse
Ganga S. Kumar, Sudipta Goswami, Subhashree Chatterjee +5
We report a remarkable bias voltage dependent specific negative capacitance in multidomain La-doped Pb(ZrTi)O (PLZT) ferroelectric capacitors. The specific nega…
Fast Interlayer Energy Transfer from the Lower Bandgap MoS2 to the Higher Bandgap WS2
Gayatri, Mehdi Arfaoui, Debashish Das +9
Energy transfer (ET) is a dipole-dipole interaction, mediated by the virtual photon. Traditionally, ET happens from the higher (donor) to lower bandgap (acceptor) material. However…
Room-temperature surface multiferroicity in YNiMnO nanorods
Shubhankar Mishra, Amritendu Roy, Aditi Sahoo +5
We report observation of surface-defect-induced room temperature multiferroicity - surface ferromagnetism ( at 50 kOe 0.005 emu/g), ferroelectricity ( 2 nC/cm…
Structural and electromechanical characterization of lead magnesium niobate-lead titanate (PMN-0.3PT) piezoceramic for energy harvesting applications
Abhishek Kumar, Amritendu Roy
Efficient mechanical energy harvesting using the principle of piezoelectric effect demands specific material-property requirements. This includes a combination of large piezoelectr…
Magnetic structure and properties of a vanthoffite mineral Na6Mn(SO4)4
Ajana Dutta, Diptikanta Swain, A. K. Bera +5
A detailed analysis of the magnetic properties of a vanthoffite type mineral Na6Mn(SO4)4 basedon dc magnetization, low temperature neutron powder diffraction and theoretical calcul…
Electric Field Control of Magnetism of Mn dimer supported on Carbon-doped-h-BN surface
Mihir Ranjan Sahoo, Saroj Kumar Nayak, Kalpataru Pradhan
Using density functional theory we show that the interaction between two Mn atoms can be tuned from anti-ferromagnetic (AFM) to ferromagnetic (FM) state by creating charge dispropo…
Can an amorphous crystallize into a high entropy alloy?
Nikhil Rai, Priyabrata Das, Srikant Gollapudi
On the premise that amorphous-HEA composites could demonstrate high toughness and resistance to embrittlement akin to the phase separating glassy-solid solution composites, we deve…
Cobalt substitution induced magnetodielectric enhancement in multiferroic Bi2Fe4O9
S. R. Mohapatra, P. N. Vishwakarma, S. D. Kaushik +3
Antiferromagnetic Bi_{2}Fe_{4}O_{9} (BFO), lightly substituted by cobalt is studied for magnetodielectricity. The substitution causes a substantial decrease in the Neel temperature…
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…
Effect of cobalt substitution on structural, impedance, ferroelectric and magnetic properties of multiferroic Bi_2Fe_4O_9 ceramics
S. R. Mohapatra, B. Sahu, M. Chandrasekhar +4
Structural, impedance, ferroelectric and magnetic properties were examined in multiferroic Bi_{2}Fe_{4(1-x)}Co_{4x}O_{9} (0x0.02) ceramics synthesized via solid-state r…
Inference of hidden structures in complex physical systems by multi-scale clustering
Z. Nussinov, P. Ronhovde, Dandan Hu +5
We survey the application of a relatively new branch of statistical physics--"community detection"-- to data mining. In particular, we focus on the diagnosis of materials and autom…

We report the observation of electric polarization in the magnetically ordered state of the Haldane chain compound, GdBaNiO, with strongly correlated magnetic and dielectri…
Giant Quasiparticle Bandgap Modulation in Graphene Nanoribbons Supported on Weakly Interacting Surfaces
Xueping Jiang, Neerav Kharche, Paul Kohl +5
In general, there are two major factors affecting bandgaps in nanostructures: (i) the enhanced electron-electron interactions due to confinement and (ii) the modified self-energy o…
