Bi-substitution-induced magnetic moment distribution in spinel BixCo2-xMnO4 multiferroic
(2009)We report the near-edge x-ray absorption spectroscopy (NEXAFS) at the Co/Mn L3,2 edge and oxygen K edge of the well-characterized Bi-substituted Co2MnO4 multiferroic samples. The evolution of peak features in NEXAFS spectra ... -
Electrically driven phase transition inmagnetite nanostructurers
(NATURE PUBLISHING GROUP, 2008-02)Magnetite (Fe3O4), an archetypal transition-metal oxide, has been used for thousands of years, from lodestones in primitive compasses(1) to a candidate material for magnetoelectronic devices(2). In 1939, Verwey(3) found ... -
Magnetization States of All-Oxide Spin Valves Controlled by Charge-orbital Ordering of Coupled Ferromagnets
(2013)Charge-orbital ordering is commonly present in complex transition metal oxides and offers interesting opportunities for novel electronic devices. In this work, we demonstrate for the first time that the magnetization states ...
