要旨

Neutron diffraction studies show that the alloy system Ce1-xLaxAl2 with x = 0.1 and 0.2 orders in the same incommensurate modulated antiferromagnetic structure as the pure compound CeAl2. The existence and concentration dependence of a commensurate extra reflection () is interpreted as being due to a modulation quenching of the CeAl2 structure. This is in contrast to the suggestion that the magnetic order of CeAl2 can be described by a triple-q structure.
