摘要
Muon-spin rotation (mu SR) measurements have been used to study the vortex lattice and its instabilities in the organic superconductors kappa-ET2Cu(SCN)(2) and beta-ET2IBr2. We ascribe the field- and temperature-dependent destruction of the vortex lattice to the large anisotropy found in these materials.
