Abstract

High-angle neutron diffraction was used to directly reveal the atomic-scale magnetic structure of a single-crystalline BiMn0:5Fe0:5O3 thin film deposited on a SrTiO3 (001) substrate. The BiMn0:5 Fe0:5O3 phase exhibits distinctive magnetic properties that differentiate it from both parent compounds: BiFeO3 and BiMnO3. A transition to long-range G-type antiferromagnetism was observed below 120K with a (1 2 1 2 1 2) propagation vector. A weak ferromagnetic behavior was measured at low temperature by superconducting quantum interference device (SQUID) magnetometry. There is no indication of the spin cycloid, known for BiFeO3, in the BiMn0:5Fe0:5O3 thin film. The neutron diffraction suggests a random distribution of Mn and Fe over perovskite B sites.
