Magneto-optic Kerr effect measurement on the probe front end shows that by controlling the saturating field direction, we can fix the probe magnetization in the specific in-plane direction. The ring is applied to the scanning tunneling microscopy and spectroscopy experiment on 6.8 ML MnFe (001), and spin contrast in the in-plane direction is demonstrated. © 2007 American Institute of Physics.Using ring-shaped and magnetically coated tungsten wire as the probe of spin-polarized scanning tunneling microscopy2378147910.1063/1.28136142-s2.0-36249028610WOS:000251003500070http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcAuth=ORCID&SrcApp=OrcidOrg&DestLinkType=FullRecord&DestApp=WOS_CPL&KeyUT=WOS:000251003500070&KeyUID=WOS:00025100350007023781479
