Role of Disorder in Governing the Magnetic Properties of Cu2IrO3
Priyanka Yadav, Sumit Sarkar, Vishal Kumar +6
CuIrO is a honeycomb iridate which has been studied recently as a candidate Kitaev quantum spin liquid. Its magnetic ground state however, has been reported to be quantum d…
Effect of antisite disorder on the magnetic and transport properties of a quaternary Heusler alloy
Srishti Dixit, Swayangsiddha Ghosh, Sanskar Mishra +8
Spin gapless semiconductors based Heusler alloys are the special class of materials due to their unique band structure, high spin polarization and high Curie temperature. These mat…
Evidence for Conical Magnetic Structure in M-type BaFe12O19 Hexaferrite: A Combined Single-Crystal XMCD and Neutron Diffraction Study
Keshav Kumar, Shrawan K. Mishra, Sanjay Singh +5
The magnetic ground state of BaFe12O19 (BFO) was investigated using X-ray absorption at 1.2 K and 1.5 K, respectively. The XMCD measurements on single-crystals of BFO in grazing in…
Colossal anomalous Hall and Nernst effect from the breaking of nodal-line symmetry in Cu2CoSn Weyl semimetal: A first-principles study
Gaurav K. Shukla, Ujjawal Modanwal, Sanjay Singh
The presence of topological band crossings near the Fermi energy is essential for the realization of large anomalous transport properties in the materials. The topological semimeta…
