Surface potential and magnetic properties of [La.sub.0.7][Sr.sub.0.3]Mn[O.sub.3] periodic arrays fabricated by direct electron beam writing

The surface potential behaviors of [La.sub.0.7][Sr.sub.0.3]Mn[O.sub.3] electron beam resist film are studied by using Kelvin probe force microscope (KFM) and their magnetic properties are studied by using magnetic force microscope (MFM). A one-step, simple and convenient alternative method is developed for fabricating nanoscale magnetic patterns, which have formed the building blocks for studying the physical properties in periodic magnetic arrays.
