| Abstract: | Fe/Cr multilayer magnetic film system of different nonmagnetic thickness is made by using magnetron sputtering. The four-probe method has been used to measure the magnetoresistance effect of this system in different magnetic fields. The saturation field method is used to give another proof. The saturation field of this system shows varying obviously with the thickness of Cr layer. A physics rule is found out that the coupling intensity varying with nonmagnetic layer thickness of ferromagnetic antiferromagnetic of Fe/Cr. |
| Keywords: | magnetron sputtering four-probe method ferromagnetic-antiferromagnetic coupling |
