Weak Itinerant Ferromagnetism (WIFM) in MAX phase compound Cr$_{1.9}$Fe$_{0.1}$GeC Open
Magnetic MAX phase compounds are important materials for studying the two-dimensional magnetism because of their layered crystallographic structure. The hexagonal MAX phase compound Cr$_2$GeC is a Pauli paramagnet, and here we report the i…

Magnetic metastability driven Anomalous Hall Effect in Fe$_{x}$TaS$_2$ Open
We have investigated the magnetic and transport properties of Fe-intercalated TaS$2$ single crystals. The material exhibits ferromagnetic order with very high anisotropy, with the $c$-axis as the easy axis. The magnetic moments of the comp…

Magnetic field induced arrested state and observation of spontaneous anomalous Hall effect in TbMn$_6$Sn$_6$ Open
The quasi two-dimensional kagome ferrimagnet TbMn$_6$Sn$_6$ is investigated for thermo-remanent magnetization and Hall effects. On cooling under a moderate magnetic field, the sample attains a magnetization value close to the saturation ma…

Suppression of Intrinsic Hall Effect through Competing Berry Curvature in Cr$_{1+δ}$Te$_2$ Open
We conducted a comprehensive analysis of the magnetic and electronic transport properties of the layered chalcogenide Cr$_{1+δ}$Te$_2$ in its single crystalline form. This material exhibits a ferromagnetic transition at a critical temperat…

Evidence of exchange-striction and charge disproportionation in the magneto-electric material Ni3TeO6 Open
The chiral magneto-electric compound Ni3TeO6 is investigated through temperature-dependent synchrotron-based powder x-ray diffraction and x-ray absorption spectroscopy between 15 to 300 K. Our work provides direct evidence for the exchange…
