Abstract
CeSe and CeTe are found by neutron diffraction to be type-II antiferromagnets with the moment along the propagation vector. The phase transitions are continuous with the critical exponent for the magnetization . This constitutes a violation of the -expansion predictions of Bak, Krinsky, and Mukamel, which hitherto have been successfully applied to a number of systems and according to which the transitions should be of first order.
