One of them is the electroless plating method. To study its potency for magnetic recording, the film’s magnetic structure is to be known. Magnetic force microscope (MFM) is a kind of scanning probe microscope (SPM). By controlling the scanning of a magnetized tip along the surface of the sample, MFM can image the magnetic field near the surface. MFM is widely used in studying magnetic head and magnetic structure of digits on disks, such as the size and shape of the digits, the recording noise of the media, the performance of rewriting and the capability to record展开更多
