Magnetic order in acentric Pb2MnO4

Research output: Contribution to journal › Article › peer-review

Abstract / Description of output

The low temperature magnetic properties of Pb2MnO4, which crystallises in an acentric but non-polar space group (P (4) over bar2(1)c) that allows piezoelectricity, have been investigated. Magnetisation measurements reveal a sharp transition to an antiferromagnetically ordered state at 18 K. Powder neutron diffraction at 1.5 K shows the spin structure to have a (000) propagation vector with Mn4+ moments of 2.74(2) mu(B) lying in the ab plane. The magnetic symmetry group is P (4) over bar '2(1)c' which permits piezomagnetism (stress-induced weak ferromagnetism). Possible 'multipiezo' properties of coupled magnetisation and electrical polarisation under mechanical stress in Pb2MnO4 are briefly discussed.
