Abstract
The effects of gas-cluster ion beam (GCIB) processing on the surface roughness, crystalline orientation texture, magnetic, and giant magneto resistance (GMR) properties of exchange biased anti-ferromagnetic (AF) oxide α-Fe2O3 bottom spin-vales (BSV) have been investigated. It was found that all of these properties were strongly influenced by the GCIB processing conditions: P1=1014, P2= 3x1014, P3=1x1015 cluster ions/cm2 of pure argon gas, and p4=5x1014 cluster ions/cm2 of H2 gas.
