摘要：

Characteristic NMR parameters of Cu-63,Cu-65 in the local magnetic field of the semiconductor mineral chalcopyrite CuFeS2 were measured in the range 26-77 K. The behavior of the Cu-63,Cu-65 NMR spectral and relaxation parameters in the local field indicated that a magnetic phase transition related to antiferromagnetic ordering of Cu2+ magnetic moments did not occur at similar to 50 K in the studied CuFeS2 sample.
