Antiferromagnetic spintronics have attracted wide attention due to its great potential in constructing ultradense and ultrafast antiferromagnetic memory that suits modern high-performance information technology. The electrical 180° switching of Néel vector is a long-term goal for developing electrical-controllable with opposite vectors as binary “0” “1.” However, the state-of-art mechanisms long been limited 90° or 120° vector, which unavoidably require multiple writing channels contradict...
Abstract Efficient spin sources with large Hall angle ( θ SH ) and long diffusion length λ SD are highly desired in the application of spintronic devices. However, due to strong spin‐orbit coupling, two targets can hardly be achieved simultaneously conventional relativistic sources, like heavy metals. Here, it is proven that collinear antiferromagnetic RuO 2 films able address this key issue break inverse relationship versus . Based on torque‐ferromagnetic resonance pumping measurements,...
The intrinsic fast dynamics make antiferromagnetic spintronics a promising avenue for faster data processing. Ultrafast resonance–generated spin current provides valuable access to dynamics. However, the inverse effect, spin-torque–driven resonance (ST-AFMR), which is attractive practical utilization of devices but seriously impeded by difficulties in controlling and detecting Néel vectors, remains elusive. We observe ST-AFMR Y 3 Fe 5 O 12 /α-Fe 2 /Pt at room temperature. vector oscillates...

Magneto-resistivity of a c-axis oriented MgB$_{2}$ thin film was studied in perpendicular and parallel magnetic fields up to $\sim $23 T with temperatures down 0.38 K. Resistive critical were determined. Large separations between irreversibility lines upper are observed. An effective quantum parameter as function temperature is proposed explain the under theoretical framework fluctuations, good agreement our experimental previously published data.
