Origin of the giant hysteresis in the temperature dependence of the microwave conductivity preliminary observed in proton-transfer and related materials were studied. We tried to clarify the origin of the hysteresis, by both macroscopic and local microwave conductivity measurements, and aimed to develop novel fast optical switches based on the proton transfer mechanisms in these materials. However, we did not find any definite evidences that the hysteresis was the manifestation of the phase transition where proton transfer was related. However, during those researches, we succeeded in obtaining new proton transfer materials, which are novel good candidates for fast optical switches. Also we found a definite route to develop high precision microwave microscope for local conductivity measurement.

研究了在质子转移和相关材料中观察到的微波电导率初步的巨型滞后的起源。我们试图通过宏观和局部微波电导率测量来阐明滞后的起源，并旨在根据这些材料中的质子传递机制开发新型快速的光学开关。但是，我们没有发现任何确定的证据表明滞后是质子转移相关的相变的表现。但是，在这些研究中，我们成功地获得了新的质子传输材料，这是快速光学开关的新型好候选者。我们还发现了开发高精度微波显微镜进行局部电导率测量的一定途径。
