Author(s): Xi-guang Wang, Tian-xiang Lu, Guang-hua Guo, Jamal Berakdar, and Hui Jing A mechanism for electrically tunable $\mathcal{P}\mathcal{T}$-symmetric magnonic lasing and antilasing is proposed along with a device consisting of a current-biased region in a magnetically ordered planar waveguide. Within the bias area, several heavy-metal wires carrying dc charge currents are per… [Phys. Rev. Lett. 137, 026701] Published Mon Jul 06, 2026
