Abstract

Developments of the high field ESR system in Kobe University is presented. Using Gunn oscillators and backward traveling oscillators (BWO), we can cover the frequency region from 30 to 1183.6 GHz with the use of InSb detector. Pulsed magnetic field up to 30 T is available and we are now trying to extend the field up to 40 T. Temperature range is from 1.8 to 300 K, Using this system, we studied S = 1/2 ladder like system Cu-2(C5H12N2)(2)Cl-4, andfound a new magnetic transition at 10.1 T at 1.8 K. The temperature dependence of ESR in Cu-2(C5H12Ni)(2)Cl-4 shows g-shift below 8 K which corresponds to the maximum of the magnetic susceptibility. The g-shift below 8 K suggests the increase of the quantum fluctuation in the system, and the role of the quantum fluctuation in Cu-2(C5H12N2)(2)Cl-4 is discussed.
