Arrott plot information


Arrott plot for a simple mean field ferromagnetic phase transition. Here, as in the Arrott's paper,[1] the relationship is demonstrated as versus , but Arrott plots are usually rearranged to versus . The value of denotes whether the temperature is above, below, or at the Curie temperature (see text).

In condensed matter physics, an Arrott plot is a plot of the square of the magnetization of a substance, against the ratio of the applied magnetic field to magnetization at one (or several) fixed temperature(s). Arrott plots are an easy way of determining the presence of ferromagnetic order in a material.[2][3] They are named after American physicist Anthony Arrott who introduced them as a technique for studying magnetism in 1957.[1]
