In a physical sense the Curie temperature (CT or T c) is defined as the temperature that marks the reversible phase crossing of ferromagnetic or ferrimagnetic materials in its high paramagnetic temperature form:
  • Above the CT, spontaneous or directed magnetization disappears from crystal domains.

  • Below the CT, magnetic materials get magnetic behavior back, i.e., the spontaneous magnetization and magnetic domains without any effect of an external magnetic field.

Therefore, CT is a material-specific temperature, above which magnetic properties of matter, solids, or rocks will change. Also remanence of magnetized ferromagnets is removed above CT (Blakely, 1995).

“CT” is named in honor of the eminent French Physicist Pierre Curie (1859–1906), who was a pioneer in crystallography, magnetism, piezoelectricity, and radioactivity and won the Nobel Prize in Physics in 1903.

A certain level in the Earth’s crust is called “Curie depth” in which temperatures are so high that the Curie temperature is...
