Abstract
We present extensive measurements of the thermal conductivity κ of a high quality single crystal of the heavy fermion superconductor UPt3 at low fields and very low temperatures (down to 16mK). Our κ(B,T) data under magnetic fields scale as a function of a single parameter x=T/TcBc2/B yielding to the first observation of the magnetic field-temperature scaling relations recently predicted for a superconductor with a line of zeros in the gap. Both the zero field and the mixed phase measurements of κ give now a consistent picture regarding the gap structure of UPt3.
