simplest and most commonly measured parameters are the Curie temperature
and the blocking temperature. In a susceptibility-measuring device the specimen
is heated until susceptibility shows a sharp rise (Hopkinson effect) immediately ...

Due to the inherent uncertainties of these Curie temperature depths, supporting
independent evidence is desirable. Possibilities include the comparison with
deep seismic soundings, gravity surveys, and petrological studies. In case the ...

The Science & Engineering of Materials
If the temperature exceeds the Curie temperature (Tc), ferromagnetic or
ferrimagnetic behavior is no longer observed. Instead, the material behaves as a
paramagnetic material. The Curie temperature (Table 20-3), which depends on
the ...

i Abstract We predict a distinctive change of magnetic properties and
considerable increase of the Curie temperature caused by the strain fields of
grain boundaries in ferromagnetic films. It is shown that a sheet of spontaneous
magnetization ...

Equation (9.2.16) does not lend itself to the evaluation of the exchange and ion
distribution parameters. T, may be defined as the temperature at which the
magnetic susceptibility becomes infinite. This paramagnetic Curie temperature
does not ...
