NiFeCo/Cu superlattices with high magnetoresistive sensitivity and weak hysteresis

The microstructure and the magetoresistive characteristics of [NiFeCo/Cu] 8 superlattices prepared by magnetron sputtering with various thickness of the buffer NiFeCr layer and exhibiting a giant magnetoresistive effect have been studied. It has been found that these nanostructures are formed with a...

Summary:The microstructure and the magetoresistive characteristics of [NiFeCo/Cu] 8 superlattices prepared by magnetron sputtering with various thickness of the buffer NiFeCr layer and exhibiting a giant magnetoresistive effect have been studied. It has been found that these nanostructures are formed with a strong or weak hysteresis depending on the structure (bcc or fcc) formed in the NiFeCr buffer layer. The method of the substantial decrease in the hysteresis loop width of the magnetoresistance by using the composite Ta/NiFeCr buffer layer has been suggested.
