Bulk magnetometry data on field application (a, b) and isothermal entropy changes (c, d) as estimated by the Maxwell relation for History A and B, respectively. History A leads to the colossal estimate of MCE, as indicated by the peak at ∼275 K.
Total isothermal entropy change on field application as observed by microcalorimetry on fragment 1. History A (a) shows non-colossal MCE and simply restricts the large entropy change to a narrower temperature range when compared with History B (b).
Latent heat component of isothermal entropy change in a mixed-phase state at 295 K (fragment 2).
