Times Cited Count：118 Percentile：95.3(Materials Science, Multidisciplinary)Single-crystal synchrotron X-ray diffraction measurements in strong magnetic fields have been performed for magnetoelectric compounds GdMnO and TbMnO. It has been found that the 
//a ferroelectric phase induced by the application of a magnetic field at low temperatures is characterized by commensurate lattice modulation along the orthorhombic 
axis with q=1/2 and q=1/4. The lattice modulation is ascribed to antiferromagnetic spin alignment with a modulation vector of (0 1/4 1). The change of the spin structure is directly correlated with the magnetic-field-induced electric phase transition, because any commensurate spin modulation with (0 1/4 1) should break glide planes normal to the 
axis of the distorted perovskite with the space group.

Management of radioactive wastes is one of the main issues of nuclear power technology. Radioactive wastes can be regarded as energy resources because of their stable radioactive emissions for long half-lives. In this study, we have attempted a direct conversion from gamma rays to electricity using solid state materials such as III-V semiconductors. The experiments were done using the gamma rays of 660keV (
Cs), 60 keV (
Am), 30 keV (
Np). The energy conversion efficiencies were 0.1-1%. Details will be reported at the conference.

We have carried out direct energy conversion from gamma rays to electricity using SiC free of toxic elements. The experiments were done using synchrotron radiation at the BL22XU beamline. To utilize radioactive wastes as an energy source, the gamma ray energies were 30 and 60 keV, corresponding to the energies from Np and Am, respectively. Also, CuK
X-rays were used to show a possibility of micro batteries using radioisotopes. The samples were Ni/SiC Schottky barrier junctions. From dark current experiments, it was found that the samples were regarded as ideal diodes on the basis of the so-called ideality factors. The electric powers under gamma rays and X-rays were found to be about 0.1
W, corresponding to efficiencies less than 0.1%. We will also show the results of energy depositions on the basis of Monte Carlo methods.
