摘要：
The present study describes the properties of magnetically hard Co50Pt50 ordered sub-micron structures. The e-beam nanolithography process and the deposition by sputtering resulted in the formation of Co50Pt50 ordered arrays 250-1000 nm sized. The thermal annealing of the samples at 650 degrees C for 30 minutes led to the crystallization of the specimen in the L1(0) phase and to their consequent magnetic hardening both in the parallel (H-c = 6.2 kOe) and in the perpendicular (H-c = 4.1 kOe) direction with respect to the film plane.
