摘要：

L1(0) ordering process for FePt thin films was examined by rapid thermal annealing with various temperatures and annealing times. A volume V of L1(0) ordered grain is calculated from grain diameter D by applying Scherrer's equation to XRD superlattice (001) peaks. A coercivity shows a linear increase until V reaches V-c = 1200 nm(3) and is similar to11 kOe in V > V-c. This behaviour of H-c is attributable to the change of domain wall pinning sites from order-disorder phase boundaries in V < V-c to both order-disorder phase boundaries and anti-phase (or c-axis variants) boundaries in V > V-c.
