Electrical resistivity measurements on a single crystal of the heavy-fermion superconductor CeCoIn5 at pressures to 4.2 GPa reveal a strong crossover in transport properties near P(*) approximately 1.6 GPa, where T(c) is a maximum. The temperature-pressure phase diagram constructed from these data provides a natural connection to cuprate physics, including the possible existence of a pseudogap.
在高达4.2吉帕斯卡的压力下对重费米子超导体CeCoIn5的单晶进行电阻率测量，结果显示在约1.6吉帕斯卡的P（*）附近，其输运性质发生了强烈的转变，此时Tc达到最大值。根据这些数据构建的温度-压力相图为铜酸盐物理提供了自然的联系，包括可能存在的赝能隙。
