| Abstract: | 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°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. |
