Quadratic short-range order corrections to the mean-field free energy
Igor Tsatskis
A method for calculating the short-range order part of the free energy of order-disorder systems is proposed. The method is based on the apllication of the cumulant expansion to th…
Coalescence of the Fermi-surface-related diffuse intensity peaks in disordered alloys
Igor Tsatskis
The possibility of disappearance of the diffuse-intensity peak splitting induced by the Fermi surface (i.e., of coalescence of the intensity maxima) with decreasing temperature is…
Non-mean-field theories of short range order and diffuse scattering anomalies in disordered alloys
Igor Tsatskis
Local, or short-range, order in disordered alloys is an important and exciting phenomenon which is quantified in electron, X-ray and neutron scattering experiments. It is discussed…
Short range order in a steady state of irradiated Cu-Pd alloys: Comparison with fluctuations at thermal equilibrium
I. Tsatskis, E. K. H. Salje
The equilibrium short-range order (SRO) in Cu-Pd alloys is studied theoretically. The evolution of the Fermi surface-related splitting of the (110) diffuse intensity peak with chan…
Simple CVM-based approximations for the configurational entropy
Igor Tsatskis
It is shown how to derive simple polynomial expressions for the variational configurational entropy starting from the cluster variation method (CVM). As an example, first six terms…
Theory of temperature dependence of the Fermi surface-induced splitting of the alloy diffuse-scattering intensity peak
Igor Tsatskis
The explanation is presented for the temperature dependence of the fourfold intensity peak splitting found recently in diffuse scattering from the disordered Cu3Au alloy. The wavev…
Origin of the anomaly in diffuse scattering from disordered Pt-V alloys
Igor Tsatskis
An explanation of the anomalous concentration dependence of diffuse scattering from the Pt-V alloy system (splitting of the (100) short-range order intensity peak with increasing P…
