| Research Abstract |
The magnetization detection type ESR technique using a commercial SQUID magnetometer has been developed. It has characteristics that ESR measurement can be done very easily and the macroscopic magnetization measurement can be done simultaneously. Moreover, we have performed the SQUID-ESR measurement under pressure successfully by using an electromagnetic wave transmission typepressure cell. In this system the popular pressure calibration method which uses the pressure dependence of the superconducting transition temperature of tin can be applicable. For Ising type magneto-dielectric material Ca_3CoMnO_6, the detailed information about the magnetic anisotropy of the system was obtained from its antiferromagnetic resonance at ambient pressure.
