![]() | Mattis, Daniel C. | Molecular-field theory with correlations | We derive an improved molecular-field theory for spins 1/2 from first principles. Formulas are obtained for use in cases when the fields, bonds, or occupation of the sites are random variables. | Molecular-field theory; Spin glasses | 1979-05 |

![]() | Symko, Orest George | Spin-glass behavior in dilute magnetic alloys with hcp structure | A simple physical model is presented for calculating the magnetization of dilute magnetic systems with hep hosts which incorporates elements of both crystal-field theory and the molecular-field theory of spin-glasses. To permit the computation of the Ruderman-Kittel-Kasuya-Yosida contribution, the i... | Spin-glass behavior; HCP structure; HCP alloys; Dilute magnetic systems; Molecular-field theory; MgMn; ZnMn | 1982-05 |
