Low-temperature physics group
There is a class of U- and Ce-based compounds that is called "heavy
fermion materials". These are strongly correlated metals that have
large effective mass, and display complex physical properties such
as superconductivity, metamagnetism and antiferromagnetism. The phenomena
are physically interesting and much effort has been made to clarify the
mechanism. In our laboratory the investigations of these "heavy fermion
materials" are made in terms of the resitivity, specific heat and
magnetization measurements. We developed a high sensitivity magnetometer
which can measure static magnetization at extremely low temperatures
down to 40 mK. Our recent activities are on metamagnetic behavior of
CeRu2Si2, magnetization process in CeB6, elastic response of URu2Si2,
non-BCS type properties in UPt3, non-Fermi liquid behavior in diluted
compounds of URu2Si2 and so on. We also use the strong magnetic
field facilities at the Institution of Solid State Physics and at Tohoku
University.
