The magnetic superconductor HoNi2B2C was studied by specific heat measurements in magnetic fields up to 2 T. The specific heat jump Delta C due to the superconducting transition at (T) over bar(c) = 8.15 K is about 140 mJ/mol K. In the scope of the Abrikosov-Gor'kov pair-breaking theory, this value is in line with a Sommerfeld value of about 19 mJ/mol K-2 as observed for the non-magnetic superconductors YNi2B2C and LuNi2B2C.

Abstract
The magnetic superconductor HoNi2B2C was studied by specific heat measurements in magnetic fields up to 2 T. The specific heat jump Delta C due to the superconducting transition at (T) over bar(c) = 8.15 K is about 140 mJ/mol K. In the scope of the Abrikosov-Gor'kov pair-breaking theory, this value is in line with a Sommerfeld value of about 19 mJ/mol K-2 as observed for the non-magnetic superconductors YNi2B2C and LuNi2B2C.File in questo prodotto:
