LiFeAs shows an unconventional mixed state with stripes of coreless vortices, each a bound state of two spatially separated half-quantum vortices, detected by transverse muon-spin spectroscopy.
This indirectly confirms that the superconducting peak is not simply a broadened one resulting from the super- position of several Gaussian distributions
