  • Magnetism near the Van Hove singularity
  • 1998
  • Ingår i: Journal of Magnetism and Magnetic Materials. - 0304-8853. ; 177-181, s. 599-601
  • Tidskriftsartikel (refereegranskat)abstract
    • We study the phase diagrams of the s-band and d-band Hubbard model in two dimensions including electron correlations. While the ferromagnetic instability in the s-band case occurs only near the Van Hove singularity, ferromagnetism is more stable in the d-band model, and the values of the Stoner parameters in transition metals are reduced below their LDA values.(14 refs)

  • A magnetic phase transition studied with high TC SQUIDs
  • 1998
  • Ingår i: Journal of Magnetism and Magnetic Materials. - 0304-8853 .- 1873-4766. ; 177, s. 519-520
  • Tidskriftsartikel (refereegranskat)abstract
    • We have used high-Tc SQUIDs to study the phase transition in a film of Mn3O4. The film was positioned on top of the SQUID, and the temperature of the film and the SQUID was varied in the range 30-60 K. By monitoring the voltage at the SQUID output we were able to observe a reproducable shift in the SQUID response in the range 30-50 K. This shift is related to the transition from the paramagnetic to the ferrimagnetic state of the Mn3O4 film.
