Quantum spin dynamics of the honeycomb magnet K${}_2$Co${}_2$TeO${}_6$ in high magnetic fields

Patrick Pilch, Laur Peedu, Urmas Nagel +6

We present terahertz spectroscopic measurements of quantum spin dynamics in the honeycomb magnet K${}_2$Co${}_2$TeO${}_6$ as a function of temperature, polarization and in an external ma…
