High pressure study on uranium compound

Tateiwa, Naoyuki; Haga, Yoshinori; Matsuda, Tatsuma; Yamamoto, Etsuji; Matsumoto, Yuji; Fisk, Z.

no journal, , 

We will report our studies on uranium compound. In particular, the details of the developments of the high pressure cell for magnetic measurements will be shown. We show some example of the measurements. In semiconducting US$$_2$$, the applying pressure induces a weak ferromagnetic state. On further increase of the pressure above the metal-insulator transition pressure of 4 GPa, the strong ferromagnetic state appears. In uranium superconductor UGe$$_2$$, we analyzed the metamagnetic transition and the maximum in the susceptibility from the view point of the spin fluctuation theory.

Neutron scattering study on uranium dicalcogenide

Metoki, Naoto; Sakai, Hironori; Suzuki, Michito; Yamamoto, Etsuji; Haga, Yoshinori; Matsuda, Tatsuma; Ikeda, Shugo*

no journal, , 

We report the neutron scattering study on UTeS in order to reveal the existence of cant antiferromagnetic structure which has been predicted to be stable as the ground state in magnetically ordered phase or field induced order of uranium dicalcogenide.

Oral presentation

Magnetocaloric effect and electronic structure of ferromagnetic perovskite BaFeO$$_{3}$$

Mizumaki, Masaichiro*; Yoshii, Kenji; Hayashi, Naoaki*; Saito, Takashi*; Shimakawa, Yuichi*; Takeuchi, Yayoi*; Takano, Mikio*

no journal, , 

BaFeO$$_{3}$$ is known to contain the rare valence state of iron, 4+. Although this system has been reported to be an antiferromagnet prepared in the conventional high pressure and high temperature method, the samples synthesized under low temperature oxidization was found to be ferromagnetic. BaFeO$$_{3}$$ shows a Curie temperature of 100 K; however, more details of magnetic properties have not been reported. In this study we report the magnetocaloric effect and the electronic structure of BaFeO$$_{3}$$.
