摘要

There are several clear experimental examples of the interaction between superconductivity and local moment magnetism in the R1221 series. Whereas these are now becoming well delineated experimentally they still need to be addressed in a detailed, theoretical manner. Some of the features that will have to be accounted for by any successful theory are (ⅰ) the effects of the CEF anisotropy on the suppression of T_c and H_(c2)(T) in the paramagnetic state and (ⅱ) the effects of the nature of the magnetic order on the superconducting ground state, specifically the effects associated with the nearly ubiquitous 0.55a~* state. In addition there is the need to account for the effects of the magnetically ordered state on the pinning of the vortex lattice, but this is probably a somewhat more complex problem.
