Abstract

High field ESR of Kagome antiferromagnets SrCrxGa12-xO19 have been observed in the submillimeter wave region from 1.8 K to 265 K. The concentration dependence was observed from x = 0.6 to x = 8.78, and all samples showed the decrease of the resonance Geld and broadening of linewidth as the temperature was decreased. As the linewidth is very broad at low temperature, for instance about 7T at 4.2 K, the measurement using high frequency was essential. The results are discussed in connection with the peculiar magnetic behaviors of the system observed by other measurements.
