Interfacial spintronic THz emission
Piyush Agarwal, Rohit Medwal, Keynesh Dongol +5
The broken inversion symmetry at the ferromagnet (FM)/heavy-metal (HM) interface leads to spin-dependent degeneracy of the energy band, forming spin-polarized surface states. As a…
Dense plasma irradiated platinum with improved spin Hall effect
Sachin Kumar, Sourabh Manna, John Rex Mohan +8
The impurity incorporation in host high-spin orbit coupling materials like platinum has shown improved charge-to-spin conversion by modifying the up-spin and down-spin electron tra…
Interfacial origin of unconventional spin-orbit torque in Py/IrMn
Akash Kumar, Pankhuri Gupta, Niru Chowdhury +6
Angle-resolved spin-torque ferromagnetic resonance measurements are carried out in heterostructures consisting of Py (NiFe) and a noncollinear antiferromagnetic quant…
Secondary spin current driven efficient THz spintronic emitters
Piyush Agarwal, Yingshu Yang, Rohit Medwal +4
Femtosecond laser-induced photoexcitation of ferromagnet (FM)/heavy metal (HM) heterostructures have attracted attention by emitting broadband terahertz frequencies. The phenomenon…
Room temperature charge-to-spin conversion from q-2DEG at SrTiO3-based interfaces
Utkarsh Shashank, Angshuman Deka, Chen Ye +6
Interfacial two-dimensional electron gas (2DEG), especially the SrTiO3-based ones at the unexpected interface of insulators, have emerged to be a promising candidate for efficient…
Disentanglement of intrinsic and extrinsic side-jump scattering induced spin Hall effect in N-implanted Pt
Utkarsh Shashank, Yoji Nakamura, Yu Kusaba +8
The rapidly evolving utilization of spin Hall effect (SHE) arising from spin-orbit coupling in 5d transition metals and alloys have made giant strides in the development of designi…
