The possibility of the coexistence of antiferromagnetic order and superconductivity in ternary rare earth compounds is examined within the framework of our previous papers on the ferromagnetic case. It is demonstrated that antiferromagnetic ordering does not destroy the superconducting state, which

โฆ Synopsis
A theoretical disc.ussion of ternary rare-earth compounds which enter the superconducting state at a temperature Tel, then ferromagnetically order at TM TM). Expressions for the phase diagram, several thermodynamic quantities, the upper critical field, and the dilution effect are derived. 9 Sakurai 1~ assumed conduction electrons mediated the spin-spin interaction (RKKY model), so that 5~ was proportional to I2N(0), where N(0) is the density of states at the Fermi energy.

In an earlier paper a theory of superconductivity in ternary rare-earth compounds which examined the effects of elastic scattering of conduction electrons by localized 4f electrons was presented. In this paper the theory is extended by treating both elastic and inelastic scattering. Expressions for
