Analytical dispersion relation for forward volume spin waves in ferrimagnets near the angular momentum compensation condition

[EN]Antiferromagnetic magnonics has become the focus of intense scientific research because of the advantages of these materials compared to ferromagnets. However, ferrimagnetic materials have received much less attention despite exhibiting similar dynamical features at the angular momentum compensa...
