Scaling Projections on Spin Transfer Torque Magnetic Tunnel Junctions
Debasis Das, Ashwin Tulapurkar, Bhaskaran Muralidharan
We investigate scaling of technologically relevant magnetic tunnel junction devices in the trilayer and pentalayer configurations by varying the cross-sectional area along the tran…
Direct Observation of the Reciprocity between Spin Current and Phonon Interconversion
Swapnil Bhuktare, Hanuman Singh, Arnab Bose +1
Spin current has emerged as a leading candidate for manipulation of spins in a nano-magnet. We here experimentally show another utility of spin current viz. it can be used for gene…
Integer, fractional and side band injection locking of spintronic feedback nano-oscillator to microwave signal
Hanuman Singh, K. Konishi, S. Bhuktare +8
In this article we demonstrate the injection locking of recently demonstrated spintronic feedback nano oscillator to microwave magnetic fields at integers as well fractional multip…

Varun K. Kushwaha, Jyoti Rani, Ashwin Tulapurkar +1
Spin-gapless semiconductors with their unique band structures have recently attracted much attention due to their interesting transport properties that can be utilized in spintroni…
Sign reversal of field like spin-orbit torque in ultrathin Chromium/Nickel bilayer
Arnab Bose, Hanuman Singh, Swapnil Bhuktare +2
In this work report unconventional sign change of field like spin orbit torque in ultra-thin Chromium(1.5nm-5nm)/Nickel(8nm) bi-layer. We performed standard spin-torque ferromagnet…
Abrupt p-n junction using ionic gating at zero-bias in bilayer graphene
Sameer Grover, Anupama Joshi, Ashwin Tulapurkar +1
Graphene is a promising candidate for optoelectronic applications. In this report, a double gated bilayer graphene FET has been made using a combination of electrostatic and electr…
Observation of Spin Nernst effect in Platinum
Arnab Bose, Swapnil Bhuktare, Hanuman Singh +2
Central focus of spintronics is concentrated on generation of pure spin current and associated spin torque. Pure spin current can be generated by spin Hall effect in heavy metals b…
Resonant spin transfer torque nano-oscillators
Abhishek Sharma, Ashwin A Tulapurkar, Bhaskaran Muralidharan
Spin transfer torque nano-oscillators are potential candidates for replacing the traditional inductor based voltage controlled oscillators in modern communication devices. Typical…
