Description

Sm-Co/Fe bilayers are deposited by DC and RF magnetron sputtering on 70 nm Cr buffered Si (100) substrate at an elevated temperature of 650 deg C. Thickness of Sm-Co and Fe is fixed as 20 nm and 10 nm, respectively. Magnetic behavior with very thin Cr layers (0.3-0.7 nm) at interface of Sm-Co and Fe is studied. All the samples showed strong exchange coupling and single phase hysteresis loops. The energy product (BH)max value is enhanced to 15% for 0.6 nm Cr layer as compared to the sample without Cr interlayer. (author)
