| 英文摘要 | We report the influence of growth parameters and post-growth annealing on the structural characterizations and magnetic properties of (ga, cr)as films. the crystalline quality and magnetic properties are sensitive to the growth conditions. the single-phase (ga, cr)as film with the curie temperature of 10 k is synthesized at growth temperature t(s) = 250 degrees c and with nominal cr content x = 0.016. however, for the films with x > 0.02, the aggregation of cr atoms is strongly enhanced as both t. and x increase, which not only brings strong compressive strain in the epilayer, but also roughens the surface. the origin of room-temperature ferromagnetism in (ga, cr)as films with nanoclusters is also discussed. |
