Factors determining surface oxygen vacancy formation energy in ternary spinel structure oxides with zinc
Yoyo Hinuma, Shinya Mine, Takashi Toyao +2
Spinel oxides are an important class of materials for heterogeneous catalysis including photocatalysis and electrocatalysis. The surface O vacancy formation energy (EOvac) is a cri…
Magnetic properties, electrical resistivity, and hardness of high-entropy alloys FeCoNiPd and FeCoNiPt
Jiro Kitagawa
We report the magnetic properties, electrical resistivity, and Vickers microhardness of as-cast and annealed high-entropy alloys (HEAs) FeCoNiPd and FeCoNiPt with the face-centered…
Flat-band solutions in -dimensional decorated diamond and pyrochlore lattices: Reduction to molecular problem
Tomonari Mizoguchi, Hosho Katsura, Isao Maruyama +1
Flat-band models have been of particular interest from both fundamental aspects and realization in materials. Beyond the canonical examples such as Lieb lattices and line graphs, a…
Competition between ferromagnetic and antiferromagnetic states in Al8.5-xFe23Ge12.5+x (0<=x<=3)
Jiro Kitagawa, Genta Yakabe, Akinori Nakayama +2
Polycrystalline Al7+xFe23Ge14-x-type orthorhombic Al8.5-xFe23Ge12.5+x (0<=x<=3) compounds were studied by X-ray diffraction measurement, metallographic examination, and magnetizati…
New room-temperature ferromagnet: B-added Pd0.75Mn0.25 alloy
Jiro Kitagawa, Kohei Sakaguchi
Mn-based room-temperature ferromagnets attract considerable attention due to their high ordered Mn moment. We have found that a Pd0.75Mn0.25 alloy with added B (Pd0.75Mn0.25Bx) sho…
Hill plot focusing on Ce compounds with high magnetic-ordering-temperatures and consequent study of Ce2AuP3
Junya Miyahara, Naoki Shirakawa, Yuta Setoguchi +3
Hill plot is a well-known criterion of the f-electron element interatomic threshold-distance separating the nonmagnetic state from the magnetic one in actinides or lanthanides. We…
Improved room-temperature-selectivity between Nd and Fe in Nd recovery from Nd-Fe-B magnet
Yusuke Kataoka, Taisuke Ono, Masami Tsubota +1
The sustainable society requires the recycling of rare metals. Rare earth Nd is one of rare metals, accompanying huge consumption especially in Nd-Fe-B magnets. Although the wet pr…
Hydrogenation of Nd-Fe-B magnet powder under a high pressure of hydrogen
Y. Kataoka, Y. Kawamoto, T. Ono +2
The hydrogenation of Nd2Fe14B under a high pressure of hydrogen has been investigated for the first time. At the heat-treatment temperature of 600 degree C, the almost complete dec…
