Laboratory of Low Temperature Materials Science Exploring and Controlling Low Temperature Properties of Materials

In this laboratory, we study the quantum phenomena occurring at low temperatures in superconducting and magnetic materials.

The current research interests are the control of superconductivity by modifying the carrier or spin concentration and the understanding of the mixed-state properties in high & low Tc superconductors, and the exploration of the ground states of electrons in cerium-based-compounds and ferromagnetic nano-granular films near absolute zero temperature. Transport and thermodynamic properties of the samples in the form of thin films, multilayer devices and substituted single crystals are investigated in the wide range of temperature and magnetic field.

This laboratory also contributes to the support works at Center for Low Temperature Science, where we supply liquid helium for various research fields and teach the low-temperature experimental techniques. Various experimental facilities for low temperature researches are open to the scientists of Tohoku University and cooperative researches are now in progress.
