Recently much work on the electronic propertes of condensed matters has been carried out under extreme conditions such as high pressure, low temperature, and high magnetic field, because new phenomena such as superconductivity and quantum phase transitions may be induced under such conditions. For this reason, we attempted to design a new high-pressure apparatus that can simultaneously be used at low temperature and in a high magnetic field. In this article, we report some new results on spin-dependent electronic properties under extreme conditions for the giant magnetoresistance (GMR) of magnetic multilayers and for the spontaneous volume magnetostriction of Invar alloy. It was found that the GMR effect in some Co/Cu multilayers is enhanced at high pressure and that the Curie temperature of Invar alloy and volume magnetostriction is strongly affected by the application of pressure.
