Aliphatic hydrocarbons dominate in the oil components at all the nine Curie temperatures, their amount increases significantly with increasing temperature.
In fact, the Curie transition has been shown to vary with processing conditions and also with the concentration of VDF and TrFE [4, 22], A slight increase of the VDF contents around 70 mol% will lead to a significant increase in Curie temperature but the melting temperature varies very slightly [4], The similar results to those observed in our study were reported by Green et al.
The Curie temperature is defined as the temperature where the characteristic of thin films transform from ferroelectric to paraelectric or vice versa.
These magnets are characterised by high saturation magnetisation and Curie temperature.
Table 1 Physical properties of gadolinium Quantity Value Curie temperature 293 K Density 7900 kg/[m.
When these objects are fired, the minerals in their clay are heated above the Curie temperature and are demagnetised.

The Curie temperature of a ferroelectric crystal has great importance as it is useful in studying various properties of the crystal.
Doping the magnetic core with other metals can change properties such as specific absorption rate (SAR) and Curie temperature.
The maximum allowable internal temperature is determined by the Curie temperature of the transformer core material, the maximum junction temperature in the switching transistors and rectification diodes and the maximum operating temperature of the capacitors.
As long as magnetized minerals aren't heated above a characteristic temperature known as a Curie temperature, the alignment of the magnetic materials contained therein remains intact.
It is observed in a small range of magnetic materials close to their Curie temperature points.
The Curie point is the temperature at which a material changes from a ferromagnetic to a paramagnetic state; this temperature is significant because a material will exhibit its greatest magnetocaloric effect near the Curie temperature.
The properties of the magnetic coating can be adjusted so that the temperature of the copper slug reaches a preset maximum temperature for the soldering iron at the point when the magnetic material reaches its Curie temperature.
For example, conventional AE sensor needs waveguide or some of heat avoidance mechanism if the testing temperature is higher than the Curie temperature of PZT.
