Abundant lattice instability in kagome metal ScVSn
Hengxin Tan, Binghai Yan
Kagome materials are emerging platforms for studying charge and spin orders. In this work, we have revealed a rich lattice instability in a kagome metal ScVSn$_6…
Atomistic Origin of Diverse Charge Density Wave States in CsVSb
Binhua Zhang, Hengxin Tan, Binghai Yan +2
Kagome metals AV3Sb5 (A=K,Rb,or Cs) exhibit intriguing charge density wave (CDW) instabilities, which interplay with superconductivity and band topology. However, despite firm obse…
Electrical switching of ferro-rotational order in nano-thick 1T-TaS crystals
Gan Liu, Tianyu Qiu, Kuanyu He +13
Hysteretic switching of domain states is a salient character of all ferroic materials and the foundation for their multifunctional applications. Ferro-rotational order is emerging…
Interplay of Structural Chirality, Electron Spin and Topological Orbital in Chiral Molecular Spin Valves
Yuwaraj Adhikari, Tianhan Liu, Hailong Wang +7
Chirality has been a property of central importance in chemistry and biology for more than a century, and is now taking on increasing relevance in condensed matter physics. Recentl…
Magnetization switching in polycrystalline Mn3Sn thin film induced by self-generated spin-polarized current
Hang Xie, Xin Chen, Qi Zhang +4
Electrical manipulation of spins is essential to design state-of-the-art spintronic devices and commonly relies on the spin current injected from a second heavy-metal material. The…
Distinct magnetic gaps between antiferromagnetic and ferromagnetic orders driven by surface defects in the topological magnet MnBi2Te4
Hengxin Tan, Binghai Yan
The magnetic topological insulator, MnBiTe, shows metallic behavior at zero magnetic fields (antiferromagnetic phase, AFM) in thin film transport, which coincides with gapl…
