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…
Large spin Hall conductivity in epitaxial thin films of kagome antiferromagnet MnSn at room temperature
Himanshu Bangar, Kacho Imtiyaz Ali Khan, Akash Kumar +3
MnSn is a non-collinear antiferromagnetic quantum material that exhibits a magnetic Weyl semimetallic state and has great potential for efficient memory devices. High-quality e…
Large spin-to-charge conversion at the two-dimensional interface of transition metal dichalcogenides and permalloy
Himanshu Bangar, Akash Kumar, Niru Chowdhury +5
Spin-to-charge conversion is an essential requirement for the implementation of spintronic devices. Recently, monolayers of semiconducting transition metal dichalcogenides (TMDs) h…
Ultrathin ferrimagnetic GdFeCo films with very low damping
Lakhan Bainsla, Akash Kumar, Ahmad A. Awad +8
Ferromagnetic materials dominate as the magnetically active element in spintronic devices, but come with drawbacks such as large stray fields, and low operational frequencies. Comp…
Energy-efficient WTa/CoFeB/MgO spin Hall nano-oscillators
Nilamani Behera, Himanshu Fulara, Lakhan Bainsla +4
We investigate a W-Ta alloying route to reduce the auto-oscillation current densities and the power consumption of nano-constriction based spin Hall nano oscillators. Using spin-to…
Fabrication of voltage gated spin Hall nano-oscillators
Akash Kumar, Mona Rajabali, Victor Hugo González +3
We demonstrate an optimized fabrication process for electric field (voltage gate) controlled nano-constriction spin Hall nano-oscillators (SHNOs), achieving feature sizes of <30 nm…
