Electrical manipulation of magnetization via current-induced spin orbit torques offers a promising route toward nonvolatile and energy efficient spintronic devices. In this work, w…
Decoupling of Spin-Orbit Torque Components in Py/W Bilayers unveiled through variation of W-resistivity
Abu Bakkar Miah, Dhananjaya Mahapatra, Soumik Aon +2
Harmonic Hall measurements were performed on a series of ferromagnetic metal/heavy metal (FM/HM) bilayers consisting of Permalloy (Py) as the FM and beta-Tungsten (W) as the HM, an…
Interface tuned Enhanced and Low Temperature Quenching of Orbital Hall Currents Induce Torque and magnetoresistance in Light Metal/Nickel Bilayers
Dhananjaya Mahapatra, Harekrishna Bhunia, Manu S Pattelath +1
We investigate orbital current induced effects arising from the orbital Hall effect in light-metal/ferromagnet bilayers. Thin films of Ti in ohmic contact with Ni were studied usin…
