UPdAl is an attractive material because of the coexistence of the antiferromagnetic order below 
= 14.5 K and superconductivity below 
= 2 K. In order to discuss the coupling between magnetism and superconductivity by resonant magnetic X-ray scattering (RMXS), nature of the resonance at each absorption edge should be clarified before the measurements across . Therefore we performed RMXS study from U 
to 
edge at 
. In addition to a huge resonance at -edge, we observed a resonant feature at 
-edge which corresponds to the transition from 
to 
orbitals, while resonance at -edge and 
-edge is rather small.

Times Cited Count：38 Percentile：80.04(Physics, Multidisciplinary)We investigated the magnetic property of typical uranium compounds by measuring the magnetic susceptibility in an extended temperature range up to about 800 K. The magnetic susceptibility follows the Curie-Weiss law for a localized 5
-electron compound UPd and a ferromagnetic insulator UFeP
. In most of the investigated compounds we observed a crossover effect of the 5
electrons from a low-temperature itinerant nature to a high-temperature localized one. This is found to be characteristic for ferromagnetic superconductors such as UGe
and UIr, and also for antiferromagnets like USb or UNiSb. To assess an extension of this characteristic property in the uranium compounds we also investigated typical 5-itinerant compounds like UGa
and UPtGa
. The crossover effect is essentially important in heavy fermion compounds such as UPt, UPdAl and URuSi. Even in the paramagnetic compound of UB, the magnetic susceptibility is not temperature-independent, but approaches a 5-localized tendency at high temperatures. Since the samples were single crystals, we were also able to trace the evolution of the magnetic anisotropy. The high-temperature anisotropic susceptibility data were analyzed on the basis of the crystalline electric field scheme.

In this review, synthetic methods of uranium and neptunium compounds mainly from solutions and their natures are summarized. For uranium, 3 compounds of trivalent, 4 compounds of tetravalent and 23 compounds of hexavalent are described in slight details. For neptunium, synthetic methods of stock solutions for pentavalent and hexavalent neptunium, 4 items (6 compounds) of trivalent, 8 items (19 compounds) of tetravalent, 28 items (29 compounds) of pentavalent, 10 items (14 compounds) of hexavalent and 5 items (9 compounds) of heptavalent are described in slight details. Furthermore, on compounds which can not be described in details, the names are listed with literatures. The materials used here have been collected during the research activities on Moessbauer spectroscopic studies of uranium and neptunium compounds, then, the reviews on Moessbauer spectroscopic studies of actinoid compounds are also listed.

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.
