Total angular momentum dichroism of the terahertz vortex beams at the antiferromagnetic resonances

A. A. Sirenko, P. Marsik, L. Bugnon +4

Terahertz vortex beams with different superposition of the orbital angular momentum $l=\pm 1$, $\pm 2$, $\pm 3$, and $\pm 4$ and spin angular momentum $\sigma =\pm 1$ were used to s…
