Abstract: 

IN THIS ARTICLE, THE EFFECTS OF FE LAYER THICKNESS ON MAGNETO RESISTANCE OF FE/CU/FE NANOSTRUCTURES WERE INVESTIGATED. THE SAMPLES WERE PREPARED BY THERMAL EVAPORATION METHOD. MAGNETORESISTANCE OF SAMPLES WITH DIFFERENT FE LAYER THICKNESS (16- 20- 30 NM) AND CONSTANT THICKNESS (13 NM) OF CU LAYER ARE MEASURED BY USING FOUR POINT PROBE AND VAN DER PAUW METHODS, IN ROOM TEMPERATURE. THE RESULTS INDICATED THAT BY INCREASING FE MAGNETIC LAYER THICKNESS, THE MAGNETO RESISTANCE OF SAMPLES REDUCED, THAT CAN BE DUE TO DECREASING SPINDEPENDENT SCATTERING OF CONDUCTION ELECTRONS. MAGNETO RESISTANCE OF SAMPLES BECOME SATURATED IN MAGNETIC FIELD OF ABOUT 500 OE.
