Distribution of Transition Temperatures in Magnetic Transformations: Sources, E ects and Procedures to Extract Information from Experimental Data
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 di erent pure phase models to systems with a DTT, the parameters of such distribution must be
known or at least estimated. In this review, the di erent sources for the existence of such distributions
and their e ects on magnetothermal properties are summarized. In addition, di erent models
proposed to extract the parameters of the corresponding DTT are discussed and extended, starting
from Weiss model, to account for other phenomenologies. Experimental results on amorphous
Fe-Nb-B and intermetallic MnCo(Fe)Ge systems are also reportedPeer reviewe
