Characterization of tips for spin-polarized scanning tunneling microscopy
Applied Physics Letters 95, (15),pp 152513/1-3 (2009)
We propose a conclusive characterization of the magnetic configuration of tips for spin-polarized scanning tunneling microscopy studies. We show that both careful tip preparation and characterization by tunneling spectroscopy need to be augmented by in-field measurements to ensure a reliable analysis of a magnetic contrast in spin-polarized scanning tunneling microscopy studies.
