  We demonstrate that magnetocaloric measurements can rapidly reveal details of
the phase diagrams of high-temperature skyrmion hosts, concurrently yielding
quantitative latent heats of the field-driven magnetic phase transitions. Our
approach addresses an outstanding issue in the phase diagram of the skyrmion
host FeGe by showing that dc magnetic anomalies can be explained in terms of
entropic signatures consistent with a phase diagram containing a single pocket
of skyrmionic order and a Brazovskii transition.
