In this letter, we synthesized epitaxialthin films of AX-type phase-pure cobalt oxynitrides (CoOxNy) by using nitrogen-plasma-assisted pulsed laser deposition and investigated their structural, electrical, and magnetic properties. The CoOxNythin films with 0\u2009\u2264\u2009y/(x\u2009+\u2009y)\u2009\u2264\u20090.63 grown on MgO (100) substrates showed a structuralphase transition from rock salt (RS) to zinc blend at the nitrogen content y/(x\u2009+\u2009y)\u2009\u223c\u20090.5. As the nitrogen content increased, the room-temperature electrical resistivity of the CoOxNythin films monotonically decreased from the order of 105\u2009\u03a9\u2009cm to 10\u22124\u2009\u03a9\u2009cm. Furthermore, we observed an insulator-to-metal transition at y/(x\u2009+\u2009y)\u2009\u223c\u20090.34 in the RS-CoOxNy phase, which has not yet been reported in Co2+/Co3+ mixed-valence cobalt oxides with octahedral coordination. The low resistivity in the RS-CoOxNy phase, on the 10\u22123\u2009\u03a9\u2009cm order, may have originated from the intermediate spin state of Co3+ stabilized by the lowered crystal field symmetry of the CoO6\u2212nNn octahedra (n\u2009=\u20091, 2,\u20265). Magnetization measurements suggested that a magnetic phase transition occurred in the RS-CoOxNyfilms during the insulator-to-metal transition. These results demonstrate that low-temperature epitaxialgrowth is a promising approach for exploring novel electronic functionalities in oxynitrides.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Applied physics letters"}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1063/1.4937431", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2015 AIP Publishing LLC."}, {"subitem_rights": "This article may be downloaded for personal use only.
