Canted spin order as a platform for ultrafast conversion of magnons.

ABSTRACT: Traditionally, magnetic solids are divided into two main classes-ferromagnets and antiferromagnets with parallel and antiparallel spin orders, respectively. Although normally the antiferromagnets have zero magnetization, in some of them an additional antisymmetric spin-spin interaction arises owing to a strong spin-orbit coupling and results in canting of the spins, thereby producing net magnetization. The canted antiferromagnets combine antiferromagnetic order with phenomena typical of ferromagnets and hold great potential for spintronics and magnonics^1-5. In this way, they can be identified as closely related to the recently proposed new class of magnetic materials called altermagnets^6-9. Altermagnets are predicted to have strong magneto-optical effects, terahertz-f
