Abstract

at room temperature for approximately one year, reopening this question. Using X-ray resonant magnetic scattering at the Ho L-3-edge we have elucidated the nature of the antiferromagnetic ordering below T-N=8.5K in Cd6Ho. The magnetic Bragg peaks are found at the charge forbidden H+K+L=2n+1 positions, referenced to the high-temperature body-centred cubic structure. In general terms, this corresponds to antiferromagnetic arrangements of the Ho moments on adjacent clusters in the unit cell as previously found for Cd6Tb.
