  Superconductivity and magnetic order strongly compete in many conventional
superconductors, at least partly because both tend to gap the Fermi surface. In
magnetically-ordered conventional superconductors, the competition between
these cooperative phenomena leads to anomalies at magnetic and superconducting
phase boundaries. Here we reveal that in Pr2Pt3Ge5 superconducting and multiple
magnetic order are intertwined within the same HT-phase space, but remain
completely decoupled. Our thermal conductivity measurements provide evidence
for normal electrons in the superconducting phase from which magnetic order
emerges with negligible coupling to electron bands that contribute to
superconductivity.
