In physics and materials science, the Curie temperature (T C), or Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can (in most cases) be replaced by induced magnetism.

Metals have a transition temperature, called the Curie point (Tc), at which the magnetic properties are drastically changed. For iron, this temperature is 770 C, above which Fe begins to transform from BCC to FCC.

Curie point, temperature at which certain magnetic materials undergo a sharp change in their magnetic properties. In the case of rocks and minerals, remanent magnetism appears below the Curie point—about 570 °C (1,060 °F) for the common magnetic mineral magnetite.

Dec 30, 2023 · Curie temperature, also known as the Curie point, is a temperature that marks a significant phase transition in magnetic materials, particularly ferromagnetic substances. Below this temperature, these materials exhibit strong spontaneous magnetization, meaning they are naturally magnetic.

The Curie temperature is 769 °C for iron, 1127 °C for cobalt and 358 °C for nickel. This temperature was named after the French physicist Pierre Curie. Table of Contents

The Curie Point of any material is the temperature above which the material will lose its ferromagnetic properties and gain paramagnetic properties. Both materials that we use in this demonstration (iron and gadolinium) are ferromagnetic at room temperature.

Pierre Curie discovered that ferromagnetic materials have a critical temperature at which the material loses their ferromagnetic behavior. This is known as its Curie Point.

For a given ferromagnetic material the long range order abruptly disappears at a certain temperature which is called the Curie temperature for the material. The Curie temperature of iron is about 1043 K. At temperatures below the Curie point, the magnetic moments are completely aligned within magnetic domains in ferromagnetic materials.

Sep 1, 2006 · I was doing some research on iron and ran across the term Curie Point. This is the temp that iron is no longer magnetic and was discovered by Pierre Curie (Madam Curies husband). My question is why do knifemakers refer to it as critical temp when the scientific term, used by physicists, metelurgists etc is the Curie point?

Iron. The specific heat flow rate of iron was measured between room temperature and 1620°C. The peak at 770°C is due to a change in magnetic properties of the material (the Curie transition). At peak temperatures of 926°C and 1399°C, two changes in the crystal structure occurred.
