Our group, composing Center for Low Temperature Science, studies 
the low-temperature electrical properties of
high-T$_{\rm c}$ superconducting and highly-correlated magnetic materials,
such as Cu-oxides, Mn-oxides and Ce-based-compounds. In addition to
understanding the basic properties of these materials, exploring and
clarifying
unknown physical phenomina in the form of thin films, multilayers and
diluted
alloys are our interests. The following subjects are now focused.
\\[-3mm]

\noindent
1) Spin injection effect on the superconducting properties in 
Cu-oxide/Mn-oxide (superconductor/ferromagnet) tunnel junctions.

\noindent
2) Studies of vortex dynamics in high-T$_{\rm c}$
superconducting films with artificially introduced defects.

\noindent
3) Studies of the ground state in diluted alloys of Ce(4f) compounds by low
temperature specific heat and transport measurements.

\noindent
4) Development of the DC magnetization measurement system down to 0.3 K.
