Accessing quasi-flat -bands to harvest large Berry curvature in NdGaSi
Anyesh Saraswati, Jyotirmoy Sau, Vera Misheneva +10
In typical rare-earth lanthanide compounds, the localized 4\textit{f}-electrons have a weak effect on the electrical conduction, limiting their influence on the Berry curvature and…
Ultrafast Dynamics of Spin-Orbit Entangled Excitons Coupled to Magnetic Ordering in van der Waals Antiferromagnet NiPS3
Sidhanta Sahu, Anupama Chauhan, Poulami Ghosh +7
Spin-orbit entangled excitons (SOEE) in two-dimensional (2D) antiferromagnets provide direct access to explore unconventional many body interactions in correlated electron systems.…
Extremely Large and Angle-Dependent Magnetoresistance in Kagome Dirac Semimetal RFeSn (R=Ho, Dy)
Susanta Ghosh, Achintya Low, Nayana Devaraj +3
We report on the electronic, magnetic, and magneto-transport properties of Fe-based kagome Dirac system, RFeSn (R = Ho, Dy). Magnetic properties study reveals an antiferrom…
Spin-reorientation Driven Temperature Dependent Intrinsic Anomalous Hall Conductivity in FeGe, a Ferromagnetic Topological Metal
Susanta Ghosh, Tushar Kanti Bhowmik, Achintya Low +1
We investigate the temperature dependence of the intrinsic anomalous Hall conductivity in FeGe, which is a ferromagnetic topological metal. We observe a significant anisotropy…
Pressure induced ferromagnetic to antiferromagnetic phase transition in transition metal chalcogenide CrTe
Asish Kumar Mishra, Souvick Chakraborty, Bidisha Mukherjee +8
We have carried out a detailed high-pressure investigation on the strongly correlated transition metal chalcogenide using Raman spectroscopy and XRD, which is ferromag…
Topological Hall effect in ferromagnetic Weyl semimetal MnGe originating in competing dipolar interaction and magnetocrystalline anisotropy
Achintya Low, Tushar Kanti Bhowmik, Susanta Ghosh +2
We report the anomalous and topological Hall effect of the ferromagnetic Weyl semimetal MnGe. We observe a significant anisotropic anomalous Hall effect (AHE) due to nonzer…
