Distribution of transition temperatures in magnetic transformations: Sources, effects and procedures to extract information from experimental data
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
The presence of a distribution of transition temperatures (DTT) is ubiquitous in materials science. It is common to ascribe deviations from theoretical pure-phase behavior to this fact. To adapt the different pure phase ...
