We have succeeded in developing a new high-pressure cell designed for measuring the absolute value of the electrical resistivity or AC susceptibility in magnetic fields at low temperatures. This pressure cell, based on a technique using modified Bridgman anvils with a Teflon capsule, can generate nearly hydrostatic pressure at least up to 6.0 GPa. The most important feature of this pressure cell is its compact body such that it can be attached to a dilution refrigerator in a superconducting magnet. One of its applications is for measurements under multi-extreme conditions, which is demonstrated by the investigation into the pressur-induced superconducting state of spin-ladder Sr14-xCaxCu24O41 single crystals.
