Spin pumping and inverse spin Hall effect in iridium oxide
Biswajit Sahoo, Koustuv Roy, Pushpendra Gupta +3
Large charge-to-spin conversion (spin Hall angle) and spin Hall conductivity are prerequisites for development of next generation power efficient spintronic devices. In this contex…

Simultaneous observation of anti-damping and inverse spin Hall effect in LaSrMnO/Pt bilayer system
Pushpendra Gupta, Braj Bhusan Singh, Koustuv Roy +4
Manganites have shown potential in spintronics because they exhibit high spin polarization. Here, by ferromagnetic resonance we have studied the damping properties of LaSr…
