Abstract. Muon-spin rotation (mSR)
measurements have been used to study the vortex lattice and its instabilities
in the organic superconductors k-ET2Cu(SCN)2
and k-ET2IBr2. We ascribe
the field- and temperature-dependent destruction of the vortex lattice
to the large anisotropy found in theses materials.
