摘要：

We report on the fabrication of high coercivity magnetic force microscopy tips for magnetic images. The CoPt permanent magnetic crystallites are prepared by magnetron sputtering followed by annealing at 700 degrees C in an argon atmosphere. We present the magnetic images of a thin-film recording head and written patterns of a recording disk taken with high H-c CoPt MFM tips. (C) 1998 Elsevier Science B.V. All rights reserved.
