The Spin Wave Stiffness Constant in Pt sub c (Mn sub 0.5 Cr sub 0.5 ) sub 1--c Alloys

Low-temp. magnetization measurements enable spin wave dispersion constant (D ) determination for Pt sub c (Mn sub 0.5 Cr sub 0.5 ) sub 1--c which qualitatively agrees with cluster model calculations. Experimental values for c = 0.70, 0.75 and 0.765 are tabled and graphed with calculated D 's an...

Zusammenfassung:Low-temp. magnetization measurements enable spin wave dispersion constant (D ) determination for Pt sub c (Mn sub 0.5 Cr sub 0.5 ) sub 1--c which qualitatively agrees with cluster model calculations. Experimental values for c = 0.70, 0.75 and 0.765 are tabled and graphed with calculated D 's and D from inelastic neutron scattering. Parameters for calculation are tabled and expressions for D are given. 12 ref.--J.V.R.
