Abstract:

The effect of a homogenous magnetic field, H₀, and a staggered magnetic field, H_Q, (arising from antiferromagnetism) on superconductivity is investigated in the case H₀ ⊥H_Q by extending our previous work treated in the case H₀ // H_Q. By studying the ground state and the second order phase transition temperature in a mean field theory, it is shown that H₀ has an additive effect of destroying the superconducting state in the presence of H_Q. The critical field, H_c, is calculated in the cases where both H₀ ⊥H_Q and H₀ // H_Q.
