An interesting theoretical prediction is that, similar as in the p-wave superconductors discussed in the next subsection, non-magnetic impurities in an antiferromagnetic superconductor cause pair breaking (Morozov 1980 Zwicknagl and Fulde 1981) whereas non-magnetic impurities in a non-magnetic superconductor are not expected to destroy superconductivity (Anderson 1959). 

An interesting question is whether the subtle effects of non-locality and, in particular, the hexagonal-square transition of the vortex lattice would be preserved in the superconducting state of magnetic superconductors such as / Ni2B2C with R = Er and Tm.

Y9C07 (Ansaldo et al. 1985) is a magnetic superconductor, but a borderline case for this review, because the magnetism is likely d-band. Its unusual behavior may be due to a bizarre crystal structure (Yvon et al. 1983).

The magnetic ordering of the lanthanide ions in superconducting systems has been a topic of active interest for many years. In conventional magnetic superconductors such as the Chevrel phase and related materials the lanthanide moments are coupled very weakly both to the metallic electrons and to each other, resulting in very low...
