Dilute Potts chain in a magnetic field
Keyword(s):
The Potts lattice gas in the presence of a uniform magnetic field is solved exactly in one dimension. For negative values of the exchange parameter, the magnetization curve exhibits two or three steps, depending on the concentration of vacancies. These steps arise as a result of the competition between the exchange interaction and the magnetic field, and are associated with different structural distributions of vacancies and the magnetic ordering of one or both sublattices.
