Saturated and Anisotropic Magnetostriction in an Altermagnet
Zhiyuan Duan, Qiyun Xu, Peixin Qin +14
Magnetostriction, a fundamental phenomenon bridging magnetism and mechanics, has enabled a broad spectrum of applications. For almost two centuries, it has been mainly investigated…
Bulk OsO2 Single Crystals: Superior Catalysts for Water Oxidation
Guojian Zhao, Zhihao Li, Ziang Meng +13
Although rutile RuO2 has been a well-known and almost the best oxygen evolution reaction (OER) catalyst, the OER properties for the similar rutile oxide OsO2 with the same group el…
Observation of Orbit-Orbit Torques: Highly Efficient Torques on Orbital Moments Induced by Orbital Currents
Hongyu Chen, Han Yan, Xiaorong Zhou +10
We study the current-induced torques in bilayers composed of a light 3d metal, chromium, and a rare-earth ferromagnet with finite orbital moments, terbium, utilizing second-harmoni…
Electric-Field-Controlled Altermagnetic Transition for Neuromorphic Computing
Zhiyuan Duan, Peixin Qin, Chengyan Zhong +12
Altermagnets represent a novel magnetic phase with transformative potential for ultrafast spintronics, yet efficient control of their magnetic states remains challenging. We demons…
Full Electrical Switching of a Freestanding Ferrimagnetic Metal for Energy-Efficient Bipolar Neuromorphic Computing
Li Liu, Peixin Qin, Xiang Wang +11
Flexible electronics and neuromorphic computing face key challenges in material integration and function retention. In particular, freestanding membranes suffer from slow sacrifici…
Freestanding Thin-Film Materials
Li Liu, Peixin Qin, Guojian Zhao +7
Freestanding thin films, a class of low-dimensional materials capable of maintaining structural integrity without substrates, have emerged as a forefront research focus. Their uniq…
