- 論文の詳細を見る
The dependences of magnetoresistance properties in Co/Cu multilayers on sputtering conditions were investigated by measuring the energy distributions of Ar+ ions and metal atoms. It was found that the incident Ar+ ion energy to the substrate increased with decreasing distance $D$ between the target and the substrate. When $D$ was changed from 5 to 11 cm, the interface roughness estimated from low-angle X-ray diffraction was improved and the magnetoresistance ratio at the first peak was increased from 31 to 42% at room temperature. These results suggest that the incident Ar+ energy affects the magnetoresistance through the modification of interface roughness.
