Effective compressible degenerate Ising model is used as a theoretical framework. Using transfer matrix formalism analytic results for the low spin -- high spin crossover were obtained. We derive the exact expressions for the fraction of molecules in the high spin state, correlation function and heat capacity. We provide analysis of parameters region where the spin crossover takes place and demonstrate how pressure changes location of the crossover. og:image:secure_url: /static/browse/0.3.4/images/arxiv-logo-fb.png twitter:image: https://static.arxiv.org/icons/twitter/arxiv-logo-twitter-square.png citation_arxiv_id: 2103.09278 citation_online_date: 2021/03/16 twitter:image:alt: arXiv logo twitter:site: @arxiv dc:title: [2103.09278] Effect of compression in molecular spin-crossover chains Content-Encoding: ISO-8859-1 citation_pdf_url: http://arxiv.org/pdf/2103.09278 Content-Type: application/xhtml+xml; charset=ISO-8859-1 X-Parsed-By: org.apache.tika.parser.DefaultParser og:type: website og:image:alt: arXiv logo twitter:title: Effect of compression in molecular spin-crossover chains og:title: Effect of compression in molecular spin-crossover chains citation_abstract: In this work, we investigate thermodynamic properties of the one-dimensional (1D) spin-crossover molecular chain being a subject of a constant external pressure.
