[HTML][HTML] On entropy determination from magnetic and calorimetric experiments in conventional giant magnetocaloric materials
JH Chen, A Us Saleheen, PW Adams… - Journal of Applied …, 2018 - pubs.aip.org
In this work, we discuss measurement protocols for the determination of the magnetic
entropy change associated with first-order magneto-structural transitions from both
magnetization and calorimetric experiments. The Cu-doped Ni 2 MnGa Heusler alloy with a
first-order magneto-structural phase transition is used as a case study to illustrate how
commonly-used magnetization measurement protocols result in spurious entropy
evaluations. Two magnetization measurement protocols which allow for the accurate …
