Giant natural optical rotation from chiral electromagnons in a collinear antiferromagnet
D. Maluski, M. Langenbach, D. Szaller +8
In NiTeO with a chiral crystal structure, we report on a giant natural optical rotation of the lowest-energy magnon. This polarization rotation, as large as 140 deg/mm, cor…

Magnetic-field-induced critical dynamics in magnetoelectric TbPO
Christoph P. Grams, Markus Grüninger, Joachim Hemberger
We report on the magnetoelectric dynamics in the linear magnetoelectric antiferromagnet TbPO studied by broadband dielectric spectroscopy. For the phase transition into the mag…
