Abstract

A neutron diffraction study on a small NpAs2 single crystal is reported. NpAs2 orders at TN = 52 K with a pure sine wave modulation propagating along a ≤100≥ direction of the tetragonal unit cell. The value of the wave vector is incommensurate with the lattice (k = ≤0.141,0,0≥) and is temperature independent down to TIC = 18.5 K where a first-order transition towards a commensurate ferromagnetic state occurs. At all temperatures the magnetic moments are aligned along the c-axis with a value of (1.45±0.1)μB at T = 5 K.
