The dots are formed by the local annealing of sputtered amorphous Co\u2013C films in regions where the laser intensity is highest. At room temperature the dots exhibit ferromagnetic order and are embedded in a paramagnetic matrix. The onset of room-temperature ferromagnetism is caused by nanoscale chemical and morphological changes during dot formation and reflects the phase separation of magnetic Co-rich clusters. The present single-step nanolithography is potentially an efficient method for fabrication of patterned magnetic arrays.<\/jats:p>","DOI":"10.1063\/1.1409948","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T12:45:28Z","timestamp":1027687528000},"page":"2606-2608","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":71,"title":["Magnetic nanodot arrays produced by direct laser interference lithography"],"prefix":"10.1063","volume":"79","author":[{"given":"M.","family":"Zheng","sequence":"first","affiliation":[{"name":"Center for Materials Research and Analysis and Department of Physics and Astronomy, University of Nebraska, Lincoln, Nebraska\u200968588-0113"}]},{"given":"M.","family":"Yu","sequence":"additional","affiliation":[{"name":"Center for Materials Research and Analysis and Department of Physics and Astronomy, University of Nebraska, Lincoln, Nebraska\u200968588-0113"}]},{"given":"Y.","family":"Liu","sequence":"additional","affiliation":[{"name":"Center for Materials Research and Analysis and Department of Physics and Astronomy, University of Nebraska, Lincoln, Nebraska\u200968588-0113"}]},{"given":"R.","family":"Skomski","sequence":"additional","affiliation":[{"name":"Center for Materials Research and Analysis and Department of Physics and Astronomy, University of Nebraska, Lincoln, Nebraska\u200968588-0113"}]},{"given":"S.
