Efficient Spin‐Orbit Torques Enabled by Vanadium‐Induced Orbital Currents for Neuromorphic Computing
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Spin‐orbit torque (SOT) provides an efficient electrical pathway for encoding spin states and underpins emerging, ultrafast, and nonvolatile spintronic memories and logic devices. Reducing the switching current density and power consumption remains a central challenge for practical applications.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

Integrative Conservation, Volume 5, Issue 2, Page 192-204, June 2026.We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The surging demand for high‐performance NdFeB magnets has made it essential to achieve ultrahigh coercivity while minimizing the consumption of heavy rare earths. To tackle this challenge, this study proposes a Dy/Tb bilayer grain boundary diffusion strategy and systematically investigates the co‐diffusion behavior of Dy and Tb.
