Abstract
The RNi 2B 2C ( R = Gd – Lu , Y ) series of compounds offers a spacious testing ground for the interaction between 4 f and conduction electrons and specifically for interactions between local magnetic moments and the superconducting ground state. In this review we will survey the effects that local moments have on the superconducting transition temperature ( T c ), the upper superconducting critical field ( H c 2 ( T ) ) and the vortex pinning and critical current density ( J c ).
