Magnons, the quasi-particles of spin waves in magnetic materials, represent the quantized form of collective spin excitations. Capable of carrying spin or orbital angular momentum, they hold promise for developing spintronic devices that operate without the limitations of Joule heating. With their nanometer-scale wavelengths and terahertz frequency operating characteristics, magnons are poised to transcend the boundaries of modern electronics. Nonetheless, the practical manipulation of magnons using electric fields poses significant challenges. Firstly, achieving effective coupling necessitates materials with robust magnetoelectric coupling characteristics, which are experimentally challenging to synthesize. Secondly, the transfer of spin or orbital angular momentum inherent in magnons must be addressed. Resolving these issues is paramount for the integration of magnons in information processing and beyond.
