摘要
New neutron-diffraction measurements on single crystals of CeAl2 confirm the previously reported incommensurate antiferromagnetic ground state with peaks at q→I=(12±α,12α,12). In addition, weaker superlattice peaks are observed at q→c=(12,12,12) and their position and temperature dependence can be explanined in terms of a multiple-q structure in CeAl2. This appears to be the first definitive evidence for a multiple-q magnetic structure. © 1979 The American Physical Society.
