โฆ Synopsis
A d-p pairing curve that is consistent with the pseudogap curve observed in experiments is found on a d-p model on phonon mechanism. On the discovery we suggest that there are two pseudogaps associated with the nearly localized d-p pairs and nearly free p-p pairs. The p-p pairs look like bosons and are responsible for superconductivities.

We report heat capacity and resistivity measurements on the ferromagnetic superconductor URhGe under high hydrostatic pressure. We find that the Curie temperature increases up to the highest pressure achieved (130 kbar). The superconducting critical temperature decreases slowly up to 20 kbar.
