Abstract
Neutron powder diffraction reveals a non-collinear antiferromagnetic a rrangement of the eight uranium magnetic moments within the unit cell of U2Rh3Si5 below T-N = 26 K. The mu(x) component of the moments order s in ferromagnetic wavy sheets stacked antiferromagnetically along x, while mu(y) exhibits a two-up, two-down configuration along y, else be ing stacked like mu(x). The magnetic structure is associated with the ordered moment mu = 1.81(5)mu(B) at T = 8.5 K.
