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…
Purely Electric-Field Control of Topological Magnetism in Two-Dimensional Magnets
Zhonglin He, Naafis Ahnaf Shahed, Kai Huang +2
Electrical control of topological magnetism is central to realizing energy-efficient topological spintronics. Yet most electric-field approaches modify the competing magnetic inter…
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…
Spin wave interactions in the pyrochlore Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interactions
V. V. Jyothis, Kallol Mondal, Himanshu Mavani +1
We study the effect of magnon interactions on the spin wave spectra of the all-in-all-out phase of the pyrochlore nearest neighbour antiferromagnet with a Dzyaloshinskii-Moriya int…
