PRESSURE EFFECT OF CURIE TEMPERATURE ON ReAl2 COMPOUNDS (1988)

Sato, K., Umehara, I., Isikawa, Y., Mori, K., Yoshida, H., Kaneko, T., ...

The Curie temperature of Gd (Al1-xCox)2 with C15 type structure increased lineally with increasing pressure and the ratios dTc / dp were obtained as 0.5, 0.38, 0.25 and 0, for the samples of x = 0,...

IV. TRANSPORTELECTRONIC STRUCTURE OF EUB6, TRANSPORT AND MAGNETIC PROPERTIES (1980)

Kasuya, T., Takegahara, K., Kasaya, M., Isikawa, Y., Fujita, T.

In non-magnetic R++B6, it is shown that the most common defect R++ vacancy can trap third hole creating a compensating conduction electron due to the narrow gap semiconductor character. The latter is...

Temperature dependence of the samarium oxidation state in SmB6 and Sm1-xLaxB6 (1980)

Tarascon, J.M., Isikawa, Y., Chevalier, B., Etourneau, J., Hagenmuller, P., Kasaya, M.

The cubic lattice parameter temperature dependence of SmB6 between 300 K and 4.2 K as well as the X-ray absorption at the LIII edge measured in the same temperature range, give direct evidence of the...

TRANSPORT AND MAGNETIC PROPERTIES OF Gd3-xOxS4 (1980)

Kamijo, A., Takase, A., Isikawa, Y., Kunii, S., Suzuki, T., Kasuya, T.

Magnetic and Transport Properties of Gd3-xOxS4 were measured. Magnetic properties are understood by a homogeneous d-f exchange model with a small Fermi energy treated before by us. Transport...

Valence transition of samarium in hexaboride solid solutions Sm 1-xMxB6 (M = Yb 2+ , Sr2+ , La3+ , Y3+ , Th4+ ) (1980)

Tarascon, J.M., Isikawa, Y., Chevalier, B., Etoumeau, J., Hagenmuller, P., Kasaya, M.

The X-ray absorption measurements at the LIII edge have been carried out at 300 K in the solid solutions Sm1-xMxB 6 (M = Yb2+, Sr2+, La3+, Y3+, Th4+). The fine structure of the edge indicates that...
