Zusammenfassung:
Anomalous properties of the magnetization, the crystal dilatation, and
other physical quantities observed in the mixed state of compounds such
as UPd2Al3 and CeRu2 suggest the occurrence of a new state near H-c2. In
such compounds with large spin susceptibility and high H-c2, a new
inhomogeneous superconducting state is theoretically predicted to occur
in high magnetic fields. In this inhomogeneous state which is shown to
be a generalized Fulde-Ferrell-Larkin-Ovchinnikov state, the order
parameter is spatially modulated, and planar nodes of the order
parameter are periodically aligned perpendicular to the vortices.
Various theoretical predictions are compared with experimental results
on UPd2Al3 and CeRu2 related to this new superconducting high-field
state.
