We report on the magnetic structure in PrCuAl as determined by powder neutron diffraction. This compound crystallizes in the hexagonal ZrNiAl-type structure and the bulk measurements indicated an antiferromagnetic order in PrCuAl below TN = 7:9 K.
Our neutron diffraction data confirmed the antiferromagnetic order below TN and revealed the propagation vector (1/3, 1/3, 1/3).
