Description

The LaFe12-xAlxMn (x=2,3,4,5,6,7) alloys have been annealed at different temperatures and for different periods. The crystal structures and magnetic properties of these compounds are investigated by X-ray diffraction and ac susceptibility measurements. The results indicate that the NaZn13-type structure is slightly sensitive to Mn-doping. However, the magnetic properties of these compounds are strongly related to the annealing temperature and period. A structural transition occurs in LaFe5Al7Mn after annealing at 773 K for about three months. A magnetic transition from ferromagnetic to paramagnetic state is found in LaFe7Al5Mn after annealing at 773 K for two months. (orig.)
