Abstract
|
|
|
|
| The correlated metal UCoGe is a weak itinerant ferromagnet with a Curie temperature T (C)=3 K and a superconductor with a transition temperature T (s)=0.6 K. We review its basic thermal, magnetic-on the macro and microscopic scale-and transport properties, as well as the response to high pressure. The data unambiguously show that superconductivity and ferromagnetism coexist below T (s)=0.6 K and are carried by the same 5f electrons. We present evidence that UCoGe is a p-wave superconductor and argue that superconductivity is mediated by critical ferromagnetic spin fluctuations. |
