Theoretical model for the superconducting and magnetically ordered borocarbides
A. Amici, P. Thalmeier, P. Fulde
We present a theory of superconductivity in presence of a general magnetic structure in a form suitable for the description of complex magnetic phases encountered in borocarbides.…

Superconductivity in a magnetically ordered background
A. Amici, P. Thalmeier, P. Fulde
Borocarbide compounds with the formula RNi2B2C show interesting superconducting and magnetic properties and the coexistence of the two phenomena. BCS theory is extended to systems…

Microscopic Theory of Magnetic Phase Transitions in HoNi_2B_2C
A. Amici, P. Thalmeier
We present a microscopic theory for the low temperature metamagnetic phase diagram of HoNi_2B_2C that agrees well with experiments.For the same model we determined the zero field g…
