Interfacial and bulk spin Hall contributions to field-like spin-orbit torque generated by Iridium
Sutapa Dutta, Arnab Bose, A. A. Tulapurkar +2
We present measurements of spin orbit torques generated by Ir as a function of film thickness in sputtered Ir/CoFeB and Ir/Co samples. We find that Ir provides a damping-like compo…
Transmission based tomography for spin qubits
Amritesh Sharma, Ashwin A. Tulapurkar
We consider a system of static spin qubits embedded in a one-dimensional spin coherent channel and develop a scheme to readout the state of one and two qubits separately. We use un…
Proposal for a graphene based nano-electro-mechanical reference piezoresistor
Abhinaba Sinha, Abhishek Sharma, Pankaj Priyadarshi +2
Motivated by the recent prediction of anisotropy in piezoresistance of ballistic graphene along longitudinal and transverse directions, we investigate the angular gauge factor of g…
Generation of n-qubit W states using Spin Torque
Amritesh Sharma, Ashwin A. Tulapurkar
We examine here a scheme to generate a W state of an n-qubit system with all-to-all pairwise exchange interaction between n qubits. This relies on sharing of superposed excitations…
Investigation of the phase separation property in LaPrCaMnO manganite
Deepak Kumar, Ashwin A. Tulapurkar, C. V. Tomy
We report a comprehensive investigation of La0.2Pr0.4Ca0.4MnO3 to clarify the micrometre scale phase separation phenomenon in the mixed valent manganite (La,Pr,Ca)MnO3. The compoun…
Band-pass Magnetic Tunnel Junction based Magnetoresistive Random Access Memory
Abhishek Sharma, Ashwin Tulapurkar, Bhaskaran Muralidharan
We propose spin transfer torque--magnetoresistive random access memory (STT-MRAM) based on magneto-resistance and spin transfer torque physics of band-pass spin filtering. Utilizin…
