Outline of Final Research Achievements |
We tried to develop measurements of thermoelectric effects in two-dimensional heavy fermion systems at low temperatures and high fields. Specially, we first made a test-probe for measuring physical properties in a wide temperature range. Next, for the high-field measurements, we equipped an existing Dewar with a 12 T superconducting magnet. In addition, we made up low-temperature cell for the measurements of Seebeck and Nernst effects in two-dimensional heavy fermion compounds that were grown on MgF2 substrate with the size of 10 mm × 5 mm. From now on, we will continue to launch our project and then move to the study of two-dimensional heavy fermion systems as soon as possible.
