Less than 50% sublattice polarization in an insulating S=3/2 kagome' antiferromagnet at low T

S. -H. Lee, C. Broholm, M. F. Collins +6

We have found weak long range antiferromagnetic order in the quasi-two-dimensional insulating oxide $KC{r}_3(OD{)}_6(S{O}_4{)}_2$ which contains Cr${}^{3+}$ S=3/2 ions on a kagomé lattice.…
