摘要：

Critical behavior of the epitaxial CrO2 film, a half metallic ferromagnet, has been determined by magnetometry with the magnetic field along the uniaxial anisotropy axis. The critical temperature has been determined to be T-C = 386.50+/-0.05 K. The critical exponents of beta =0.371+/-0.005 and gamma =1.43+/-0.01 indicate that CrO2 is a Heisenberg ferromagnet.
