Abstract
The magnetic phases of the UAs 1- x Se x single crystals were investigated by neutron diffraction. For x ⩽ 0.40 an incommensurate antiferromagnetic ordering ( k = [00 k]; m k | k ) is observed below T N down to T IC. At T N the k-value varies continuously with x; in decreasing temperature the k-value approaches the commensurate value below T IC. At T IC an incommensurate-commensurate transition leads to type-IA ( k = 0.500) for 0.05 < x ⩽ 0.30, to type-I ( k = 1) for x ⩽ 0.05 (with subsequent transition to type-IA), and to squaring-up of (5+, 4-) structure for x = 0.40. For x ≳ 0.50 the ordering is ferromagnetic.
