Abstract

High field ESR measurements of S = 1/2 one-dimensional quantum antiferromagnetic (AF) system BaCu2(Si1-xGex)2O7 have been performed using powder samples and pulsed magnetic field. High field electron paramagnetic resonance at 352 GHz and 86 K enabled us to determine the x dependence of g-values even when we used the powder samples. The x dependence will be discussed in connection with the crystal field. Moreover, antiferromagnetic resonances of x = 0 and x = 1 samples below TN were observed and their frequency-field relations suggest the existence of Dzyaloshinsky-Moriya interaction.
