Interplay of Orbital Degeneracy and Vacancies in Stabilizing Collinear Magnetic Order in CrTe

Prasanta Chowdhury, Jyotirmoy Sau, Mohamad Numan +7

CrTe, a two-dimensional van der Waals ferromagnet, displays a contested magnetic structure, poised between collinear and non-collinear spin configurations. In this wor…

Atypical Ferrimagnetism in NiNbO

Jhuma Sannigrahi, Roumita Roy, Richard Waite +6

Ferrimagnetism typically emerges from chemically distinct magnetic ions or the same element at two inequivalent crystallographic sites, rendering unequal moments. In contrast, Ni4N…

Weak Itinerant Ferromagnetism (WIFM) in MAX phase compound CrFeGeC

Suman Mondal, Mohamad Numan, Kurt Kummer +2

Magnetic MAX phase compounds are important materials for studying the two-dimensional magnetism because of their layered crystallographic structure. The hexagonal MAX phase compoun…

Magnetic Metastability driven Anomalous Hall Effect in FeTaS

Mohamad Numan, Prasanta Chowdhury, Sanat Adhikary +5

We report here the observation of robust thermoremanent magnetization (TRM) in Fe-intercalated TaS single crystal FeTaS, which develops upon cooling under a moderate…

Magnetic field induced arrested state and observation of spontaneous anomalous Hall effect in TbMnSn

Tamali Roy, Prasanta Chowdhury, Mohamad Numan +4

The quasi two-dimensional kagome ferrimagnet TbMnSn is investigated for thermo-remanent magnetization and Hall effects. On cooling under a moderate magnetic field, the samp…

Suppression of Intrinsic Hall Effect through Competing Berry Curvature in CrTe

Prasanta Chowdhury, Jyotirmay Sau, Mohamad Numan +5

We conducted a comprehensive analysis of the magnetic and electronic transport properties of the layered chalcogenide CrTe in its single crystalline form. This materia…
