  • Interplay of structure, magnetism and resistivity of La0.5Ca0.54MnO3+x
  • 2000
  • Ingår i: Physics Letters A. - 0375-9601 .- 1873-2429. ; 271:02-jan, s. 121-127

    • The structure of La0,5Ca0,5MnO3 is well known for T> 250 K and T( 150 K. But in the intermediate region some structure characteristics are difficult to understand [1]. This Letter studies in this temperature region the interrelation between structure and the experimental data like magnetism and resistivity on the basis of a vibron-electron dynamic equilibrium hypothesis. It has been shown that behavior of paramagnetic-to-ferromagnetic transition can be explaned in the framework of this hypothesis.

  • Pressure effect on electrical properties and photoluminescence spectra of solid C60 and C70 fullerenes
  • 2001
  • Ingår i: Frontiers of High Pressure Research II: Application of High Pressure to Low-Dimensional Novel Electronic Materials. - Dordrecht : Springer/Kluwer. - 9781402001604 ; , s. 483-491
  • Konferensbidrag (refereegranskat)abstract
    • Electrical resistivity of crystalline and disordered fullerite samples obtained by static high-pressure-high-temperature treatment of C-60 and C-70 at P = 12.5 GPa and T = 820-1500 K was investigated in the temperature range of 2.4-300 K, Room-temperature activation energy of charge carriers was found to be in the range 40-200 meV. T-3/2 and T-4 dependencies of conductivity versus temperature were revealed both in crystalline and disordered structures. Photoluminescence spectra of C-60 samples treated at P = 13 GPa. T = 770-1470 K show 50 nm short-wave length shift of characteristic 750 nm PL band.

  • Infinite lifetime for the starlike dynamics in Hele-Shaw cells
  • 2004
  • Ingår i: Proceedings of the American Mathematical Society. - 0002-9939 .- 1088-6826. ; 132:9, s. 2661-2669
  • Tidskriftsartikel (refereegranskat)abstract
    • One of the folklore questions in the theory of free boundary problems is the lifetime of the starlike dynamics in a Hele-Shaw cell. We prove precisely that, starting with a starlike analytic phase domain Omega(0), the Hele-Shaw chain of subordinating domains Omega( t), Omega(0) = Omega(0), exists for an infinite time under injection at the point of starlikeness.
