Abstract Scope |
Spin crossover is a thermally-induced change of spin state from low spin (LS) to high spin (HS) that can occur at temperatures up to and beyond room temperature, when crystal field splitting of d-orbitals is of the order of kBT. In previous work, we gave the first direct experimental evidence of a giant, low pressure barocaloric effect (BCE) in a molecular complex around its spin crossover (SCO) transition [1]. In this presentation, we will examine the ways in which the multiple external parameters known to influence the SCO transition temperature, TSCO, can be used to drive so-called multi-caloric effects.
