Successive incommensurate spin orderings and excitations in multiferroic SrMnGe2O6
Claire V. Colin, Lei Ding, Eric Ressouche +8
Anisotropic multiferroic properties of SrMnGe2O6 pyroxene single crystals were systematically investigated by means of magnetization, heat capacity, pyroelectric current measuremen…
Quantum Tunneling in Half-Integer-Spin Kagome-Lattice Langasites
A. Zorko, F. Bert, P. Mendels +9
Employing the muon spin relaxation technique we evidence temperature independent magnetic fluctuations persisting down to the lowest temperatures in the samarium-based () ka…
Internal-strain mediated coupling between polar Bi and magnetic Mn ions in the defect-free quadruple-perovskite BiMnMnO
A. Gauzzi, G. Rousse, F. Mezzadri +10
By means of neutron powder diffraction, we investigated the effect of the polar Bi ion on the magnetic ordering of the Mn ions in BiMnMnO, the counterp…
