Abstract/OtherAbstract:
The local effect of the Josephson vortices on the vortex lattice melting process in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} crystals in the presence of an in-plane field H_{ab} is studied by differential magneto-optical imaging. The melting process is found to commence along the Josephson vortex stacks, forming a mesomorphic phase of periodic liquid and solid lamellas, the direction and spacing of which are controlled by H_{ab}. The reduction of the local melting field H_{m} along the Josephson vortex stacks is more than an order of magnitude larger than the reduction of the average bulk H_{m} by H_{ab}.
