Transition metal oxides with triangular metallic sublattices: From multiferroics to low-dimensional magnets

Publication date: Available online 11 September 2018Source: Comptes Rendus ChimieAuthor(s): Bernard Raveau, Vincent Caignaert, Vincent Hardy, Mohammad Motin SeikhAbstractThe very recent studies of two classes of transition metal oxides with a triangular metallic sublattice are reported. The first class of materials concerns the swedenborgite CaBaCo4O7 family, which is shown to be a ferrimagnetic multiferroic with a gigantic-induced electrical polarization, and the second one deals with the spin chain oxides of the Sr4Mn2CoO9 type, which have been found to behave as single chain magnets and single ion magnets. These materials that exhibit a potential for applications in the field of memory devices and quantum computation pave the way for future investigations in these systems.
