Emergence of a Non-van der Waals Magnetic Phase in a van der Waals Ferromagnet
Bikash Das, Subrata Ghosh, Shamashis Sengupta +12
Manipulation of long-range order in two-dimensional (2D) van der Waals (vdW) magnetic materials (e.g., CrI, CrSiTe etc.), exfoliated in few-atomic layer, can be achieved vi…
Shubnikov-de Haas and de Haas-van Alphen oscillation in Czochralski grown CoSi single crystal
Souvik Sasmal, Gourav Dwari, Bishal Baran Maity +3
Anisotropic transport, Shubnikov-de Haas (SdH), and de Haas-van Alphen (dHvA) quantum oscillations studies are reported on a high-quality CoSi single crystal grown by the Czochrals…
Weak antilocalization and Shubnikov-de Haas oscillations in CaCuSb single crystal
Souvik Sasmal, Vikas Saini, Nicolas Bruyant +5
Quantum oscillations in both linear and Hall resistivities and weak antilocalization (WAL) are barely observed in bulk single crystals. Here we report the transport properties of a…
Nanoscale devices with superconducting electrodes to locally channel current in 3D Weyl semimetals
Biswajit Datta, Jaykumar Vaidya, Subhamoy Ghatak +5
We report on the fabrication of nano-devices on the \hkl[-1 0 1] surface of a Weyl semimetal, a macroscopic crystal of TaAs, and low-temperature transport measurements. We can impl…
Emergence of well screened states in a superconducting material of the CaFeAs family
Ram Prakash Pandeya, Anup Pradhan Sakhya, Sawani Datta +10
Coupling among conduction electrons (e.g. Zhang-Rice singlet) are often manifested in the core level spectra of exotic materials such as cuprate superconductors, manganites, etc. T…
Behavior of gapped and ungapped Dirac cones in an antiferromagnetic topological metal, SmBi
Anup Pradhan Sakhya, Shiv Kumar, Arindam Pramanik +10
We studied the behavior of nontrivial Dirac fermion states in an antiferromagnetic metal SmBi using angle-resolved photoemission spectroscopy (ARPES). The experimental results exhi…
Structural anomaly in superconductivity of CaFe2As2 class of materials
Ram Prakash Pandeya, Arindam Pramanik, Anup Pradhan Sakhya +5
Quantum transitions in Fe-based systems are believed to involve spin, charge and nematic fluctuations. Complex structural phase diagram in these materials often emphasizes importan…
Anisotropic Physical Properties of the Kondo Semimetal CeCuAs
Lukas Cvitkovich, Diego A. Zocco, Gaku Eguchi +6
The recently proposed novel materials class called Weyl-Kondo semimetal (WKSM) is a time reversal invariant but inversion symmetry broken Kondo semimetal in which Weyl nodes are pu…
Weak antilocalization in a noncentrosymmetric CaAgBi single crystal
Souvik Sasmal, Rajib Mondal, Ruta Kulkarni +2
We report on the single crystal growth and transport properties of a topological semimetal CaAgBi which crystallises in the hexagonal type structure with the non-centrosymmet…

The present article reports the governing influence of substituting the M2 site in nanoscale MFe2O4 spinel ferrites by different magnetic metals Fe,Mn,Co,Ni on magnetorheological a…
Magnetocrystalline anisotropy in the Kondo lattice compound CeAgAs
Rajib Mondal, Rudheer Bapat, S. K. Dhar +1
We report on the single crystal growth and anisotropic physical properties of CeAgAs. The compound crystallizes as on ordered variant of the HfCuSi-type crystal structure a…
Extreme magnetoresistance induced by Zeeman effect-driven electron-hole compensation and topological protection in MoSi
M. Matin, R. Mondal, N. Barman +2
The magnetoresistance is the magnetic field induced change of electrical resistivity of a material. Recent studies have revealed extremely large magnetoresistance in several non-ma…
