High-Field Terahertz Spin Resonance in Cr${}_2$O${}_3$ above the Spin-Flop Transition

Kaiyang Huang, Yuto Kinoshita, Natsuki Kanda +4

We report single-shot terahertz time-domain spectroscopy of Cr${}_2$O${}_3$ in pulsed magnetic fields up to 30 T. Well above the spin-flop field, in the 20-30 T range, the resonance fr…
