Near-zero effective magnetization enabling ultra-low threshold currents in spin Hall micro-oscillators
A. Koujok, H. Kurebayashi, K. Yamamoto +6
The paper shows that engineering a near‑zero effective magnetization dramatically lowers the current needed to drive spin Hall oscillators, enabling micrometer‑scale devices with u…
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…
Evidence for single variant in altermagnetic RuO2(101) thin films
Cong He, Zhenchao Wen, Jun Okabayashi +6
Altermagnetism presents intriguing possibilities for spintronic devices due to its unique combination of strong spin-splitting and zero net magnetization. However, realizing its fu…
