摘要：

In alpha Fe2PO5 the octahedrons containing the Fe2+ and Fe3+ ions share a common face. These octahedrons form zig-zag chains of alternating spin parallel to the b axis. Exchange interactions between Fe2+ and Fe3+ are ferromagnetic: this is confirmed by neutron diffraction. The alternating spin chain model, ignoring interactions between chains, was used. Our results show that alpha Fe2PO5 exhibits ferromagnetic behavior.
