Abstract :
The fabrication of nanostructures in niobium thin films has been developed. Optimisation of process technology concerned pattern generation in e-beam sensitive AZ PF514 resist and pattern transfer by reactive ion etching (RIE) in CCl2F2/H2 plasma. By adjusting the process, parameters Nb bridge structures with dimensions down to 80 nm and anisotropic rectangular arrays of antidots of 125-nm average diameter have been fabricated. Magnetisation curves measured on the structured Nb films strongly suggest formation of anisotropic vortex lattices in the system of anisotropic array of antidots.
