Abstract
We studied the crystal and magnetic structure of the oxygen deficient perovskite YSrCuFeO5+y. The structure was refined from neutron powder diffraction data by assuming both substitutional and displacement diso rder. Three-dimensional (3D) antiferromagnetism with T-N = 400 +/- 10 K occurs and all the magnetic peaks were indexed with two propagation vectors k(1) = [1/2 1/2 1/2] and k(2) = [1/2 1/2 1] from 300 down to 2 K.
