Use of megagauss fields for solid state physics investigations-"Kapitsa" series in Sarov

Movement to the area of limiting magnetic fields opens unique possibilities for new effects searching. This also requires high resources, limiting implementation of ultrahigh magnetic fields into experimental practice. There are only 5 laboratories nowadays able to perform experiments in magnetic fields of megagauss range. The record magnetic field of 2800 T was obtained in the laboratory of ultra-high magnetic fields of RFNC-VNIIEF, Sarov. Earlier decision was made to open the unique bases for Russian and foreign this laboratory was classified, but in 1997 the scientists During this period we performed 4 International Scientific and Practical Conferences "Kapitsa". Within the framework of these Conferences we performed 8 joint programs with: Germany (3), France (3), Italy (1) and Great Britain (1). More than 33 samples were studied in 16 explosive experiments. Great work was done on magnetic susceptibility measurement and determination of magnetic phase transitions of the 1 st order in highly correlated systems: LaCoO/sub 3/, LaMnO/sub 3/, (LaSrCa)/sub 14/Cu/sub 24/O/sub 41/, YNi/sub 5-x/Cu/sub x/, semiconductors: HgSe:Fe, FeSi, high-spin metalloorganic clusters: Mn12, Mn6, Fe8, Fe10, V15. Cyclotron resonance (CR) is one of the perspective methods of semiconductors fundamental parameters investigations. Cyclotron resonance measurements in semiconductors GaN and GaAs on the wavelength of 10 /spl mu/m were performed in Experimental Series "Kapitsa-3" and "Kapitsa-4".
