Information × Registration Number 0208U005308, 0106U005791 , R & D reports Title The development of the complex methods of the property investigations of the systems, which contain oxides and chalcogens and have the alternative type of conductivity. popup.stage_title Head Victor N. Uvarov, Доктор фізико-математичних наук Registration Date 09-04-2008 Organization Institute for metal physics NAS Ukkraine popup.description2 The realized design has as the purpose of the substantial improvement and application of procedures of a X-ray fluorescent spectroscopy and theoretical calculations with use of a cluster of the powerful computers.The materials which are cotaining the lantan and oxide of 3d-metals and materials, which are containing one chalcogen and three another elemetal components have been investigated.The completion of this design had allowed to improve the precision of adjustment, sensitivity and stability of the spectrometer's operations conciderably. The especial program was created for management by an experiment. The procedure of performance acceleration of the theoretical electronic structure calculations is discribed. The possible reasons of the metal-insulator temperature transitions in these substances have been analysed. At the end of the report 12 basic deductions were made according results of the completed work. The list of reference (79 positions) is a termination of the report.
