Quadratic to linear magnetoresistance tuning in TmB4
Sreemanta Mitra, Jeremy Goh Swee Kang, John Shin +7
The change of a material's electrical resistance (R) in response to an external magnetic field (B) provides subtle information for the characterization of its electronic properties…
Degeneracy of the 1/8 plateau and antiferromagnetic phases in the Shastry-Sutherland magnet TmB4
Jennifer Trinh, Sreemanta Mitra, Christos Panagopoulos +3
The 1/8 fractional plateau phase (1/8-FPP) in Shastry-Sutherland Lattice (SSL) spin systems has been viewed an exemplar of emergence on an Archimedean lattice. Here we explore this…
Dimensional crossover in the quasi-one-dimensional superconductor TlMoSe
S. Mitra, A. P. Petrović, D. Salloum +5
Long-range order in quasi-one-dimensional (q1D) arrays of superconducting nanowires is established via a dimensional crossover from a fluctuating 1D regime to a phase-coherent 3D g…
Probing the superconducting gap symmetry of -PdBi: A penetration depth study
S. Mitra, K. Okawa, S. Kunniniyil Sudheesh +3
We report measurements of the in-plane London penetration depth in single crystals of the -PdBi superconductor --- the -phase counterpart of the putative topologica…
Finite Size Effect in Amorphous Indium oxide
Sreemanta Mitra, Girish C. Tewari, Diana Mahalu +1
We study the low temperature magneto-transport properties of several highly disordered amorphous Indium oxide(a:InO) samples. Simultaneously fabricated devices comprising a 2-dimen…
Negative Magnetoresistance in Amorphous Indium Oxide Wires
Sreemanta Mitra, Girish C Tewari, Diana Mahalu +1
We study magneto-transport properties of several amorphous Indium oxide nanowires of different widths. The wires show superconducting transition at zero magnetic field, but, there…
Evidence for a Finite Temperature Insulator
M. Ovadia, D. Kalok, I. Tamir +3
In superconductors the zero-resistance current-flow is protected from dissipation at finite temperatures (T) by virtue of the short-circuit condition maintained by the electrons th…
Observation of spin-glass behavior in nickel adsorbed few layer graphene
Sreemanta Mitra, Oindrila Mondal, Sourish Banerjee +1
Nickel-adsorbed graphene was prepared by first synthesizing graphite oxide (GO) by modified Hummers' method and then reducing a solution containing both GO and . EDX analy…
Magnetodielectric effect in nickel nanosheet-Na-4 mica composites
Sreemanta Mitra, Amrita Mandal, Anindya Datta +2
Nickel nanosheets of thickness 0.6 nm were grown within the nanochannels of Na-4 mica template. The specimens show magnetodielectric effect at room temperature with a change of die…
Ferromagnetic behavior of ultrathin manganese nanosheets
Sreemanta Mitra, Amrita Mandal, Anindya Datta +2
Ferromagnetic behaviour has been observed experimentally for the first time in nanostructured Manganese. Ultrathin ( 0.6 nm) Manganese nanosheets have been synthesized inside…
Enhanced magnetic anisotropy of Nickel nanosheet prepared in Na-4 mica
Sreemanta Mitra, Amrita Mandal, Anindya Datta +2
Nanosheets of nickel with thickness equal to 0.6 nm have been grown within the interlayer spaces of Na-4 mica. The sheets are made up of percolative clusters of nanodisks. Magnetiz…
Magnetodielectric effect of Graphene-PVA Nanocomposites
Sreemanta Mitra, Oindrila Mondal, Dhriti ranjan Saha +3
Graphene-Polyvinyl alcohol (PVA) nanocomposite films with thickness were synthesized by solidification of PVA in a solution with dispersed graphene nanosheets. Electrical…
Tunneling conduction in graphene/(poly)vinyl alcohol composites
Sreemanta Mitra, Sourish Banerjee, Dipankar Chakravorty
Graphene/(Poly)vinyl alcohol (PVA) composite film with thickness were synthesized by solidification of a PVA solution comprising of dispersed graphene nanosheets. The close…
