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 material…
Unconventional transport behavior in the Quaternary Heusler compounds CoFeTiSn and CoFeVGa
Snehashish Chatterjee, Subarna Das, S. Pramanick +4
We report here the electrical transport and magnetic properties of the newly synthesized quaternary Heusler compound CoFeTiSn and CoFeVGa. We observe a striking change in the elect…
Probing the core and shell contributions to exchange bias in Co/CoO nanoparticles of controlled size
D. De, Oscar Iglesias, S. Majumdar +1
Coupling at the interface of core/shell magnetic nanoparticles is known to be responsible for the exchange bias (EB) and the relative sizes of core and shell components are suppose…
Multiple first order transitions and associated room temperature magneto-functionality in Ni2.048Mn1.312In0.64
S. Pramanick, P. Dutta, S. Chatterjee +2
Present work reports on the observation of multiple magnetic transitions in a Ni-excess ferromagnetic shape memory alloy with nominal composition NiMnIn$_{0.64}…
Spin correlated dielectric memory and rejuvenation in relaxor ferroelectric CuCrS2
A. Karmakar, K. Dey, S. Chatterjee +2
CuCrS2, a Heisenberg antiferromagnet with layered edge sharing triangular lattice, exhibits a spiral magnetic order. Dielectric (E) and polarization studies show magnetoelectric (M…
