| Research Abstract |
In this study, we have developed a prototype apparatus for ther-mo-magnetic effect (Nernst effect) measuring in pulsed magnetic fields. Tip of the measuring probe is configured sapphire substrate with good thermal conductivity as a heat bath, on film strain gauge small a heater and an epoxy resin to mount the sample. Although we could not measure the Nernst phenomena on iron-based superconductors by using this measurement system, we succeeded to measure transport phenomena on a semimetal bismuth.
