Two methods for calculating the superconducting transition critical temperature of superconductor / ferromagnetic metal heterostructures in the dirty limit are compared. The first method relies on an approximation where the order parameter is assumed to be constant within each superconducting layer. The second method does not use any approximations and involves a numerical iterative process where the critical temperature and the order parameter distribution are jointly searched for in each iteration. Using these methods, we study various heterostructures involving a ferromagnetic and superconducting layers, including case where the ferromagnetic layer is split into domains.
