Exceptionally high Verdet constant in gold nanodisc arrays
Gajendra Mulay, Shraddha Choudhary, Ashwin A Tulapurkar +4
Magneto-optical effects in non-magnetic noble metals can be greatly enhanced by leveraging the in-plane Lorentz force at engineered plasmonic resonances. We demonstrate a 2D array…
Out-of-plane angle resolved second harmonic Hall analysis in perpendicular magnetic anisotropy systems
Akanksha Chouhan, Abhishek Erram, Ashwin A. Tulapurkar
Spin orbit torques (SOT) are used to manipulate magnetization of ferromagnets in heavy metal / ferromagnetic bilayers and thus are technologically relevant from magnetization switc…
Gate Voltage-Controlled Magnetic Anisotropy Effect on Pt-Porphyrin functionalized single-layer graphene
Ambika Shanker Shukla, Abhishek Erram, Heston Alfred Mendonca +3
We report a novel approach to engineering large voltage-controlled magnetic anisotropy (VCMA) and enhanced spin-orbit coupling (SOC) at the interface of single-layer graphene (SLG)…
Shape Anisotropy Enabled Field Free Switching of Perpendicular Nanomagnets
Akanksha Chouhan, Heston A. Mendonca, Abhishek Erram +1
Spin Orbit Torque-Magnetic Random Access Memory (SOT-MRAM) is being developed as a successor to the Spin transfer torque MRAM (STT-MRAM) owing to its superior performance on the me…
Ultrahigh Frequency and Multi-channel Output in Skyrmion Based Nano-oscillator
Abhishek Sharma, Saumya Gupta, Debasis Das +2
Spintronic nano-oscillators can generate tunable microwave signals that find a wide range of applications in the field of telecommunication to modern neuromorphic computing systems…
