Abstract
The magnetic ordering temperature of some rare-earth-basedheavy-fermion compounds is strongly pressure dependent and can becompletely suppressed at a critical pressure, pc, making way fornovel correlated electron states close to this quantum criticalpoint. We have studied the clean heavy-fermion antiferromagnetsCePd2Si2 and CeIn3 in a series of resistivity measurementsat high pressures up to 3.2 GPa and down to temperatures in the mKregion. In both materials, superconductivity appears in a smallwindow of a few tenths of a GPa on either side of pc. We presentdetailed measurements of the superconducting and magnetictemperature-pressure phase diagram, which indicate thatsuperconductivity in these materials is enhanced, rather thansuppressed, by the closeness to magnetic order.
