    Structural and magnetic properties of Ni2-xCoxMnSb (x: 0.00, 0.25, 0.50 and 1.00) Heusler alloys: The relationship between Curie temperature and lattice parameter
    (Elsevier Sci Ltd, 2019) Ak, F.; Oz, E.; Saatci, B.
    Ni2-xCoxMnSb Heusler alloys were fabricated by arc melting process. The endothermic/exothermic reactions with increasing temperature were determined by DTA analysis and it was found that the chancing Co concentration in the system causes the change in the reaction temperatures. The temperature dependence of the magnetization from base temperature to 600 K, a crucial value for the Curie temperature, and lattice parameters of the samples were determined. It was suggested that increasing Co in the samples causes the change of the grain formation and the increasing Co concentration in the system also causes the change of the Curie temperature values with decreased the lattice parameters.
