DEVELOPMENT OF THE HIGH FIELD MAGNETO-OPTICAL MEASUREMENT SYSTEM WITH A ROTATIONAL CAVITY FOR THE STUDY OF ORGANIC CONDUCTORS

摘要

We have developed a new magneto-optical measurement system with a rotational cavity. It consists of a millimeter vector network analyzer and a 15T solenoid type superconducting magnet and it can go down to 1.5 K. The rotational cavity can be used in the transmission configuration and the rotation can be performed up to almost 360 degrees in 1 degree precision. We will show the magneto-optical measurement results of β"-(BEDT-TTF)(TCNQ) using our new system. We observe the quasi-two-dimensional periodic orbit resonance (POR) in β"-(BEDT-TTF)(TCNQ). The Fermi surfaces of this system will be discussed.
