Abstract
Neutron diffraction measurements show that in the temperature range from 7.4 to TN=10.4 K the magnetic structure of HoCu2 is a commensurably modulated a-axis collinear structure with a wave vector q1=1/3a*. Below 7.4 K an additional structure component develops and the low temperature magnetic structure of HoCu2 is found to be an incommensurably modulated non-collinear structure characterized by wave vectors q1=/13;a*, q2=qcc* and 2q2, where a* and c* are reciprocal lattice vectors of the orthorhombic structure and qc=0.300±0.005. The corresponding moment components μ-q1, μq2 and μ2q2 lie along the a, b and b directions of the orthorhombic crystal lattice, respectively.
