Application Of The Weiss Molecular Field Theory To The Lattice Of The B-Site Spinel, Wayne Edmund Holland
Application Of The Weiss Molecular Field Theory To The Lattice Of The B-Site Spinel, Wayne Edmund Holland
Masters Theses
"The Weiss molecular field theory has been applied to the lattice of the B-site spinel. The forms of the ordering temperatures and the asymptotic Curie temperature have been determined for a sixteen-sublattice model with collinear spins. The theory has been applied to the problem of determining the exchange integrals for systems of the form Aa₁₋ₓAbₓCr₂X₄ and ACr₂Xa4(1-y)Xb4y. The theoretical results have been compared to the experimental data for the systems Hg₁₋ₓCdₓCr₂S₄, Zn₁₋ₓCdₓCr₂Se₄, and CdCr₂S4(1-y)Se4y in an attempt to determine the exchange integrals"--Abstract, page ii.
