摘要：
The phase transitions in the three-dimensional standard weakly diluted 5-state Potts model on a simple cubic lattice are examined by computer simulation. The calculations are carried out for systems with periodic boundary conditions and spin concentrations p = 1.0; 0.90; 0.85; 0.8. The value of the tricritical point pt in the phase diagram is found using Binder cumulants and histogram analysis of the data. Magnetic structures corresponding to different temperature regimes in the vicinity of the tricritical point are obtained.
