Observation of Magnetic-Anisotropy Crossover and High-Temperature Skyrmions in the Dirac Magnet Fe3Ge with a Distorted Kagome Lattice
Yalei Huang, Xiaowei Lv, Bin Li +13
Topological materials that simultaneously host robust high-temperature skyrmions and nontrivial electronic band structures have attracted tremendous interest owing to their distinc…
Emergence of multiple quasi-ferromagnetic magnon modes induced by strong magnetoelastic coupling in single crystal
Sourabh Manna, Felix Fuhrmann, Sergio Rodríguez Fernández +8
We investigate the magnetization dynamics of single crystals across the spin-reorientation phase transition using broadband microwave absorption spectroscopy up to 87.5 G…
Electrically Accessible Metamagnetic Transition via a Doping-Induced Low-Energy Magnetic State in Antiferromagnetic Insulator RFeO3
Wanting Yang, Haohuan Peng, Ziming Wang +7
Low-energy antiferromagnetic phase transitions offer an appealing platform for low-power spintronic functionalities, yet their direct electrical access in insulating antiferromagne…
Observation of cooperative strong coupling between optical phonon and crystal-field excitations in a pseudo Jahn-Teller system
Fangliang Wu, Xiaoxuan Ma, Zhongwei Zhang +6
Cooperative interactions between localized electronic excitations and crystal lattice are central to the emergence of complex structural phases in materials. However, the scaling r…
Altermagnetic magnon transport in the \textit{d}-wave altermagnet \ch{LuFeO3}
Edgar Galindez-Ruales, Wanting Yang, Tobias Dannegger +11
Altermagnets exhibit a spin-split band structure despite having zero net magnetization, leading to special magnonic properties such as anisotropic magnon lifetimes and field-free s…
Terahertz stimulated parametric downconversion of a magnon mode in an antiferromagnet
Zhuquan Zhang, Yu-Che Chien, Man Tou Wong +6
In condensed matter systems, interactions between collective modes offer avenues for nonlinear coherent manipulation of coupled excitations and quantum phases. Antiferromagnets, wi…
