Times Cited Count：0 Percentile：0(Physics, Multidisciplinary)We report a mean-field theoretical study of a triangular magnet NiGaS. Using the localized Wannier functions obtained from a band calculation, the most stable magnetic state was found to be spiral with the incommensurate structure, consistent with the result from neutron diffraction. The Ni-site Coulomb interaction was not strong (U about 2 eV). The spin value at the Ni site was also not so large about 1.1 mb. These results mean that the hybridization between Ni and S may play an important role. The dynamical spin correlation function was found to in accord with the results from neutron scattering.

Since it is desired to enhance availability and safety of nuclear power plants operation and maintenance by removing human factor, there are many researches and developments for intelligent operation or diagnosis using artificial intelligence(AI) technique in the Frontier Research. In this development, We have been developing an autonomous operation and maintenance system for nuclear power plants by substituting AI's. On the other hand, Ship Research Institute(SRI) have been developing a monitoring system for cooperative function of distributed systems in the autonomous operation and maintenance systems. In this report, we have studied telecommunication methods between PNC and SRl to combine the autonomous operation and maintenance system and its monitorillg systan. As the result, we have confinned a proper performance of that telecommunication facility by the test via public telephone line or Internet.
