摘要：
The Fe0.95Co0.05Si2 semiconducting film has been successfully grown on glass substrate by magnetron sputtering at substrate temperature of 637 K and then thermal annealing at 823 K for one hour in high vacuum. The Raman data and high Seebeck coefficient suggested that the beta-Fe0.95Co0.05Si2 semiconducting film was achieved. Room temperature ferromagnetism was observed, and the ferromagnetic phase transition was at about 380 K. The possible reason for the ferromagnetism of the beta-Fe0.95Co0.05Si2 semiconducting film was discussed.
