Optical and magneto-optical properties of thin Zn_(1-x)Mn_xO films doped

摘要

Zn_(1-x)Mn_xO thin films doped by nitrogen with a low concentration of Mn (1%) were prepared by using ultrasonic spray pyrolysis. Optical absorption and magnetic circular dichroism (MCD) measurements were conducted in order to study the optical and magnetic properties of Zn_(0.99)Mn_(0.01)O. The exciton lines are dominant in the spectra of these samples, which indicate a high crystal quality of the films.Magneto-optical measurements show a significant MCD signal at the band edge of Zn_(0.99)Mn_(0.01)O.
