Near-zero effective magnetization enabling ultra-low threshold currents in spin Hall micro-oscillators
A. Koujok, H. Kurebayashi, K. Yamamoto +6
Reducing the electrical current required to excite magnetization dynamics is a central challenge, e.g. for energy-efficient magnonic devices or oscillator-based computing. Spin Hal…
Dynamical stability by spin transfer in nearly isotropic magnets
Hidekazu Kurebayashi, Joseph Barker, Takumi Yamazaki +9
Spin transfer torques (STTs) control magnetisation by electric currents, enabling a range of nano-scale spintronic applications. They can destabilise the equilibrium magnetisation…
Antisymmetric interlayer exchange coupling spontaneously built in synthetic antiferromagnetic structure by film growth
Takeshi Seki, Hiroto Masuda, Varun K. Kushwaha +1
The antisymmetric-type long-range exchange interaction between two ferromagnetic layers through a nonmagnetic layer, called antisymmetric interlayer exchange coupling (AIEC), has r…
Non-equilibrium Magnon Engineering Enabling Significant Thermal Transport Modulation
Takamasa Hirai, Toshiaki Morita, Subrata Biswas +13
Thermal conductivity, a fundamental parameter characterizing thermal transport in solids, is typically determined by electron and phonon transport. Although other transport propert…
Observation of charge-to-spin conversion with giant efficiency at NiFe/BiWO interface
Saikat Das, Satoshi Sugimoto, Varun Kumar Kushwaha +2
Magnetization switching using spin-orbit torque offers a promising route to developing non-volatile memory technologies. The prerequisite, however, is the charge-to-spin current co…
Structure, magnetic and transport properties of epitaxial thin films of equiatomic CoFeMnGe quaternary Heusler alloy
Varun K. Kushwaha, Jyoti Rani, C. V. Tomy +1
Future spintronics requires the realization of thin film of half-metallic ferromagnets having high Curie temperature and 100\% spin polarization at the Fermi level for potential sp…
Possible spin gapless semiconductor type behaviour in CoFeMnSi epitaxial thin films
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…
