Magnon blocking effect and magnonic skin effect shown in antiferromagnetically coupled heterojunction

Spin waves, or magnons, as the elementary excitation of the magnetic system, can transfer spin angular momentum, which provides wide prospects for the Non-volatile, low-energy-consumption, high-speed and small-size microelectronic devices in the post-Moore period. Magnonics, encompassing the generation, transport and manipulation of magnons, has become the latest development direction of spintronics and an emerging discipline of condensed matter physics.
