Nanoscale resolution in microscopy characterization has become crucial for state-of-the-art science and technology. We have developed a Magneto-optical Scanning Near-Field Optical Microscope (MO-SNOM), and it has demonstrated to be a powerful tool to study local magnetic properties [1,2]. One of the critical steps in producing a reliable instrument and consistent images is the fabrication of the microscope tip. This work presents concepts and results on tip processing by chemical etching on FS-SN-3224 optical fibers from 3M. The quality of the tips produced was tested on magnetic multilayers presenting exchange-bias coupling.
