The purpose of the present work is to study the NiO cluster formation in Ni3Al alloys by field ion microscope and atom probe (AP-FIM). A polycrystal Ni3Al (B-do
In Sm_2Fe_17-_x.Mx(M=Al, Ga), there was observed a kind of spin-reorientation with temperature. and in (Sm1_-xTm_x)_2Fe_14Al_3, the anisotropy field HA increase
