Abstract:
A systematic study of the dependence of the local magnetic moment, M, on the Fe-Pn layer separation has beencarried out. Within the Ehrenfest classification of orders of phase transition, we propose a continuous (> 2) phasetransition for studying the dependence of M on the Fe-Pn layer separation. Our model is tested with availableexperimental data.
