Basic Science

The group has a long tradition of using neutron and synchrotron scattering techniques to obtain information about atomic structures and dynamic properties of phonons and spinwaves of magnetic and superconducting solids. The main interest are

  • Experimental input to the clarification of why High Temperature Superconductors works.
  • Interaction between magnetism and superconductivity in REB2Ni2C superconductors with focus on quadropolar ordering.
  • Measurements of phonon dispersion curves of thermoelectric Ba8Ga16Ge30 single crystals in order to explain the low thermal conductivity.
  • Measurements of atomic and magnetic structures in magneto electrioc materials such as LiNiF4
  • Measure diffraction from the flux line lattice of superconductors using small angle neutron scattering to explain shape and correlation of flux lines.

 

  • Characterize basic properties of solids in applied fields up to B = 16 Telsla and temperatures T = 2-650 K using Cryogenic Limited superconducting magnet.
    • Magnetization
    • AC-susceptibility
    • Resistivity
    • Specific heat

 

  • Measure pinning properties of superconductors (MgB2, Nb3Sn, YBa2Cu3O6+x & Bi2Sr2Ca2Cu3O10+x)
  • Determination of AC losses in superconductors
