Within the Ehrenfest classification of orders of phase transition, we propose a continuous (>2) phase transition for studying the dependence of M on the Fe-Pn layer separation. Our model is tested with available experimental data.}, number={1}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, author={Ekuma, Chinedu E and Chukwuocha, Ephriam O and Onyeaju, Michael C}, year={2023}, month={Nov.}, keywords={Pnictide superconductors, 74.20.De, 74.40, 74.70.Kn, 82.35.Jk, Continuous phase transition, Ehrenfest theory, Euler, N, Ginzburg, Magnetic moment, Lagrange equation, Fe, Landau theory, 64.60.av} }
