It is found that the magnetization and the Curie temperature of B2-FeAl-np decrease as the transverse field increases. A similar decrease in the magnetization and the Curie temperature of B2-FeAl is experimentally observed by Plazaola et al. with the increase (27.5%, 30%, 32.5% and 35%) of the Al content in B2-FeAl. These theoretical and experimental results revealed that the increase of the Al content in B2-FeAl-np causes an increase in the transverse field of B2-FeAl-np. Thus, the magnetization and the Curie temperature of B2-FeAl-np decrease. However, the ferromagnetic and antiferromagnetic spin splitting of paramagnetic Fe and Al atoms is obtained by a non-zero external magnetic field (H = 0.25) at T > T-C.eninfo:eu-repo/semantics/openAccessArticle1391202410.12693/APhysPolA.139.202-s2.0-85102504396Q3WOS:000620916200004Q4
