摘要: High field ESR of Kagome antiferromagnets SrCr x Ga 12- O 19 have been observed in the submillimeter wave region from 1.8 K to 265 K. The concentration dependence was =0.6 =8.78, and all samples showed decrease resonance broadening linewidth as temperature decreased. As is very broad at low temperature, for instance about 7 T 4.2 K, measurement using high frequency essential. results are discussed connection with peculiar magnetic behaviors system by other measurements.
