Theory of pressure effects and the correlated-electron behaviour of UTe
The behaviour of US, USe and UTe is quite well explained on the basis of decreasing f-electron itinerancy and increasing correlation between electrons. Recent experiments show that with increasing pressure, the Curie temperature T(C) goes through a maximum, for both USe and UTe. Theoretical values of T(C) are calculated using a correlated-electron theory. Corrections are required to the low-temperature ordered moment and ordering temperature, from a computer simulation of the charge fluctuations resulting from increased hybridisation.
