Curie point

A transition temperature marking a change in the magnetic or ferroelectric properties of a substance, especially the change from ferromagnetism to paramagnetism. Also called Curie temperature.

[After Pierre Curie.]

Curie point


Curie temperature

(General Physics) the temperature above which a ferromagnetic substance loses its ferromagnetism and becomes paramagnetic
[C20: named after Pierre Curie]

The self-calibration is triggered fully automatically at a temperature of 118 deg C (Curie point of the integrated reference), a process typically occurring during each steam sterilisation (SIP) of the plant.
Pierre Curie long ago discovered that as he progressively heated magnetized materials in his laboratory, they lose their magnetization at a certain temperature, now known as the Curie point. For iron, which carries magnetism in lavas, the Curie point occurs at 770[degrees]C (1418[degrees]F).
TrustSens has a built-in, precision ceramic reference based on the Curie Point of the reference material; that is, the temperature at which its ferromagnetic properties abruptly change.
Tivey: Magnetism does not exist above a temperature called the Curie point, 580 degrees Celsius for ocean crust.

It is preferable for the magnetic material that is used in a magnetic refrigerator to have a Curie point close to room temperature, along with a large magnetocaloric effect.
This "Curie point" temperature is when the skin effect begins to decrease, again permitting the current back into the conductive core of the heater and repeating the cycle.
In our research we measured the temperature dependencies from room temperature to temperature of Curie point.
Copolymers containing 50-80 mol% VDF are of special interest, because they exhibit a Curie point which is absent in pure PVDF and show a marked increase in polarization [11].
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.
