High quality La0.67Ca0.33MnO3 (LCMO) film was deposited via a novel pulsed electron deposition technique on SrTiO3(100) single crystal substrate.The micro-bridge with different widths was fabricated by using electron beam lithography (EBL) technique and their transport properties were studied.For the micro-bridges with width of 2 and 1.5 μm, the insulator-to-metal transition temperature (Tp) keeps un-changed compared with the film.For the micro-bridges with width of 1 p.m, the Tp shifts towards the lower temperature by 50 K.When the width decreases down to 500 nm, the insulator-to-metal transition disappears.The magnetoresistance be-havior of these micro-bridges was studied, and the results show that the low field magnetoresistance (LFMR) decreases and the high field magnetoresistances (HFMR) keep almost unchanged as the width of micro-bridge is reduced.
