Zusammenfassung:
Muon spin relaxation measurements in zero magnetic field on several
polycrystalline samples provide evidence that superconductivity and
magnetic order do not coexist on a microscopic scale but develop
inhomogeneously in Ce 1+xCu 2+ySi 2. The distribution of magnetic and
superconducting domains depends on the temperature and sensitively on
variations of the stoichiometry. Superconductivity sets in first in the
paramagnetic domains and, on further cooling, reduces the magnetically
ordered volume fraction. However, in all samples down to T=60 mK
considerable portions remain magnetic.
