Investigation of magnetic order influenced phonon and electron dynamics in MnBiTe and Sb doped MnBiTe through terahertz time-domain spectroscopy
Soumya Mukherjee, Anjan Kumar NM, Subhadip Manna +4
MnBiTe, the first topological insulator with inherent magnetic ordering, has attracted significant attention recently for providing a platform to realize several exotic…
Anisotropic magneto-photothermal voltage in Sb2Te3 topological insulator thin films
Subhadip Manna, Sambhu G Nath, Samrat Roy +8
We studied longitudinal and Hall photothermal voltages under a planar magnetic field scan in epitaxial thin films of the Topological Insulator (TI) Sb2Te3, grown using pulsed laser…
Enhancement of spin to charge conversion efficiency at the topological surface state by inserting normal metal spacer layer in the topological insulator based heterostructure
Sayani Pal, Anuvab Nandi, Shambhu G. Nath +5
We report efficient spin to charge conversion (SCC) in the topological insulator (TI) based heterostructure () by using spin-pumping techniq…
Modulating Spin Current Induced Effective Damping in Heterostructures by a Systematic Variation in Resistivity of the Sputtered Deposited films
Soumik Aon, Sayani Pal, Subhadip Manna +2
Utilizing the spin-induced pumping from a ferromagnet (FM) into a heavy metal (HM) under the ferromagnetic resonance (FMR) condition, we report an enhancement in effective damping…
