Abstract
The temperature dependence of the magnetic critical scattering above T N and the staggered magnetization below TN has been measured in the longitudinally modulated antiferromagnets thulium and erbium using neutron diffraction. The transitions which occur at TN=57. 65+or-0.10 K in thulium and at TN=86.04+or-0.20 K the erbium appear to be continuous second-order transitions. As longitudinally modulated antiferromagnets thulium and erbium would be expected to belong to the d=3, n=2 unversality class of the d=3 XY model.
