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.2017http://zaguan.unizar.es/record/7567810.1088/1361-6501/aa925ehttp://zaguan.unizar.es/record/75678oai:zaguan.unizar.es:75678info:eu-repo/grantAgreement/EUR/COST/CM1301info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-1-Rinfo:eu-repo/grantAgreement/ES/MINECO/MAT2015-69725-REDTMEASUREMENT SCIENCE & TECHNOLOGY 28, 12 (2017), 125401 [7 pp]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
