被引用回数:9 パーセンタイル:95.72(Materials Science, Multidisciplinary)UTe is a recently discovered spin-triplet superconductor. One of the characteristic features of UTe is a magnetic field ()-boosted superconductivity above 16 T when H is applied exactly parallel to the axis. To date, this superconducting (SC) state has not been thoroughly investigated, and the SC properties as well as the spin state of this high- SC (HHSC) phase are not well understood. In this letter, we performed AC magnetic susceptibility and nuclear magnetic resonance measurements and found that, up to 24.8 T, the HHSC state has bulk nature and is quite sensitive to the angle and that its SC character is different from that in the low- SC (LHSC) state. The dominant spin component of the spin-triplet pair is along the axis in the LHSC state but is changed in the HHSC state along the axis. Our results indicate that -induced multiple SC states originate from the remaining spin degrees of freedom.

被引用回数:86 パーセンタイル:86.04(Chemistry, Multidisciplinary)We synthesized two high-pressure polymorphs PbNiO with different structures, a perovskite-type and a LiNbO-type structure, and investigated their formation behavior, detailed structure, structural transformation, thermal stability, valence state of cations, and magnetic and electronic properties. A perovskite-type PbNiO synthesized at 800C under a pressure of 3 GPa crystallizes as an orthorhombic GdFeO-type structure with a space group Pnma. The reaction under high pressure was monitored by an in situ energy dispersive X-ray diffraction experiment, which revealed that a perovskit-type phase was formed even at 400C under 3 GPa.

汚染水処理から発生する様々な廃棄物に対して、低温処理技術(セメント固化等)による固化処理プロセスを適用する場合の適用可能性を簡易に検査するため、セメントの比熱および様々な化学物質の発熱量測定により、廃棄物を混練した固化体の温度予測値を算出した。これまでに開発した画像判定装置による熱画像と温度予測値の組み合わせにより、廃棄物混練時の固化体温度を簡易に判定できる方法を整理した。
