curie point list

The Curie Point, also referred to as the Curie Temperature, is the specific temperature at which a material undergoes a significant change in its magnetic properties. Named after the physicist Pierre Curie, this point marks the temperature at which a material transitions between different magnetic phases.

Below the Curie Point, a material tends to exhibit spontaneous magnetic ordering, meaning its atoms or molecules align in a coordinated magnetic orientation. This leads to the material being magnetic, often in a ferromagnetic, ferrimagnetic, or antiferromagnetic state, depending on the material’s atomic structure and interactions.

Conversely, above the Curie Point, the material’s magnetic ordering weakens, and it becomes less magnetic. The thermal energy at these higher temperatures disrupts the alignment of the magnetic moments within the material, causing it to transition into a paramagnetic or even diamagnetic state.

In essence, the Curie Point is a critical temperature that defines the boundary between a material’s magnetic and non-magnetic behaviors. It is a crucial parameter for understanding and utilizing the magnetic properties of various substances in technological applications such as electronics, magnetic storage, and materials science.

Certainly, here’s a list of some common materials along with their Curie points:

  1. Iron (Fe): ~770°C (~1418°F)
  2. Nickel (Ni): ~354°C (~669°F)
  3. Cobalt (Co): ~1121°C (~2050°F)
  4. Gadolinium (Gd): ~20°C (~68°F)
  5. Dysprosium (Dy): ~85°C (~185°F)
  6. Neodymium (Nd): ~310°C (~590°F)
  7. Samarium (Sm): ~107°C (~225°F)
  8. Curie-Weiss Law: The Curie-Weiss law is used to describe the behavior of magnetic susceptibility in materials as they approach their Curie points.

Remember that these values are approximate and can vary depending on factors such as impurities, crystal structure, and other environmental conditions. The Curie point is a critical temperature for understanding the magnetic properties of materials.
