Multi-phase competition in quantum $XY$ pyrochlore antiferromagnet CdYb${}_2$Se${}_4$: zero and applied magnetic field study

K. Guratinder, Jeffrey G. Rau, V. Tsurkan +9

We study magnetic behaviour of the Yb${}^{3+}$ ions on a frustrated pyrochlore lattice in the spinel {\CYS}. The crystal-electric field parameters deduced from high-energy inelastic…
