Times Cited Count:1 Percentile:7.13(Materials Science, Multidisciplinary)We searched for an experimental condition of crystal growth for a ferromagnetic superconductors of UGe and URhGe. Samples were prepared for both polycrystalline and single crystals, which were arc-melted and grown by the Czochralski-pulling method in a tetra-arc furnace, respectively. Annealing is an important process to enhance sample-quality, namely the residual resistivity ratio. We tried to anneal the samples under various temperatures, which were wrapped by the Ta-foil and vacuum-sealed in the quartz ample, together with the solid state electrotransport method in ultra-high vacuum. The highest residual resistivity ratio was 900 for UGe and 41 for URhGe.

We succeeded in growing a high-quality single crystal of UIr with the monoclinic PbBi-type structure by the Czochralski pulling method in a tetra-arc furnace. The magnetization measurement indicates that UIr is an Ising-like ferromagnet with the Curie temperature = 46 K. The magnetic moment is found to be oriented along the [1 0 /U. The magnetic property, reflected in the magnetic susceptibility, electrical resistivity, Hall coefficient and thermoelectric power, is highly anisotropic. We also observed the de Haas-van Alphen (dHvA) oscillation. All the detected branches have large cyclotron effective masses ranging from 9.6 to 32 . They are consistent with the electronic specific heat coefficient =49 mJ/Kmol.

Fermi surfaces of uranium compounds are investigated by de Haas-van Alphen (dHvA) effect. Band calculations well reproduce the Fermi surfaces of non-magnetic itinerant systems such as USi, UC, UAl. Fermi surfaces of the heavy fermion compounds, where the strong correlation between carriers are important, are also explained by band calculations, except for their unusually large mass enhancement. We have also observed dHvA oscillations in the superconducting mixed states in heavy fermion superconductors such as URuSi, UPdAl and CeRu. A significan field dependence of cyclotron effective mass and scattering life time were observed.

Times Cited Count:20 Percentile:67.13(Physics, Condensed Matter)The angular dependence of de Haas-van Alphen effect has been measured to reveal the electronic structure of filled skutterudite PrRuSb. The angular dependence of de Haas-van Alphen frequency of PrRuSb is in good agreement with that of LaRuSb. Compared with PrFeP, no anomalous enhancement of cyclotron effective mass has been observed in this system. This change of electronic structure is attributed to the difference in the hybridization strength, which is expected from the large difference in the lattice parameters.

The topology of the Fermi surface is found to be neary cylindrical, reflecting the unique tetragonal structure. Observed branches are well explained by the 4f-itinerant band model. The cyclotron masses are large, 20-30 m0, which are one order larger than the corresponding band masses.
