## Description

- description: 'Spin-crossover (SCO) compounds are fascinating materials that exhibit
    colorful phase transitions induced by temperature, pressure, photoirradiation,
    etc. The elastic interaction arising from lattice distortion due to molecular
    size difference between the low-spin (LS) and high-spin (HS) molecules plays a
    crucial role in the cooperativity of these transitions. This elastic interaction
    gives rise to both short-range and effective long-range interactions. Elastic
    frustration leads to competition between these interactions, resulting in a variety
    of thermodynamic and metastable phases (Fig. 1) [1-6]. We studied the properties
    of metastable phases in several SCO systems by constructing elastic interaction
    models [1-6]. Through phase diagram analysis, we identified diverse patterns of
    thermally induced SCO transitions with stepwise behavior [4–6]. Additionally,
    we examined stepwise SCO transitions in a core-shell SCO nanocomposite model consisting
    of two different SCO compounds [6]. We analyzed two cases: the core has a lower
    transition temperature than the shell, and the core has a higher transition temperature.
    In this presentation, we discuss the thermodynamic properties of symmetry-breaking
    phases and the stepwise SCO transition patterns that emerge from these interactions.'
