Functionalized Akiyama tips for magnetic force microscopy measurements
Resumen: In this work we have used focused electron beam induced deposition of cobalt to functionalize atomic force microscopy Akiyama tips for application in magnetic force microscopy. The grown tips have a content of ˜90 % Co after exposure to ambient air. The magnetic tips were characterized using energy dispersive x-ray spectroscopy and scanning electron microscopy. In order to investigate the magnetic properties, current loops were prepared by electron beam lithography. Measurements at room temperature as well as 4.2 K were carried out and the coercive field of ˜6.8 mT of the Co tip was estimated by applying several external fields in the opposite direction of the tip magnetization. Magnetic Akiyama tips open new possibilities for wide-range temperature magnetic force microscopy measurements.
