Simultaneous Antiferromagnetic Order and Spin-Glass-Like Behavior in MnAsO 4 .

-The magnetic structures of the simple new solid MnAsO 4 and the secondary phase Mn 2 AsO 7 are determined using pulsed neutron powder diffraction. MnAsO 4 orders magnetically at 14 K with an unusual antiferromagnetic structure as only half of the Mn 3+ spins are ordered and the remaining "idle" spins show a spin-glass-like behavior. The antiferromagnetic minority phase Mn 2 As 2 O 7 orders at 10 K. -(ARANDA, M.
