Description
A vortex lattice consisting of a pinstripe pattern of vortex chains has been observed in untwinned YBa2Cu3O7-δ crystals. This state is present when the field is tilted away from the c axis, and is oriented with the chains confined to the plane defined by B and c. The chains arise from the attractive part of the vortex-vortex interaction in this geometry as described within the ansiotropic London equations. For B>Φ0/2πλ 2 the chains merge into an oriented vortex lattice. From the fitted value of λ, we can conclude that the microscopic irreversibility temperature is T/Tc∼0.92 for B∼20 G
