Conditions for Altermagnetism in RuO2
Himanshu Mavani, Zhonglin He, Evgeny Y. Tsymbal
The magnetic ground state of rutile RuO2 remains disputed, raising a central question: under what structural and chemical conditions can this material support altermagnetism? We ad…
Termination-Preserved Ultra-high Tunneling Magnetoresistance in Altermagnetic KV2Se2O
Junnan Guo, Himanshu Mavani, Wenhui Fang +6
Altermagnets exhibit nonrelativistic spin splitting without net magnetization, establishing a new platform for next-generation spintronic devices. Although altermagnetic tunnel jun…
Exchange Frustration and Topological Magnetism in Electrostatically Doped SrRuO3
Naafis Ahnaf Shahed, Himanshu Mavani, Zhonglin He +3
Magnetism in transition-metal systems emerges from exchange interactions that depend sensitively on carrier density. Yet leveraging this sensitivity to deliberately engineer exchan…
Competing Antiferromagnetic Phases in Multiferroic Wurtzite Transition-Metal Chalcogenides
Himanshu Mavani, Mohamed Elekhtiar, Kai Huang +2
Antiferromagnetic (AFM) spintronics offers a pathway toward electrically controllable spin-based devices beyond ferromagnets. Here, we identify wurtzite MnX (X = S, Se, Te) as a fa…
Two-dimensional antiferromagnets with non-relativistic spin splitting switchable by electric polarization
Himanshu Mavani, Kai Huang, Kartik Samanta +1
Spin-split antiferromagnets have significance for antiferromagnetic (AFM) spintronics due to their momentum dependent spin polarization which can be exploited for the control and d…
