The Curie-Weiss law is applicable to ferromagnetic and antiferromagnetic materials near their Curie temperature for ferromagnets or Néel temperature for antiferromagnets. This law describes how the susceptibility (χ) of a ferromagnet or antiferromagnet changes with temperature (T). Specifically, the Curie-Weiss law is presented mathematically as:

[ chi = frac{C}{T – T_c} ]

where:

– (chi) is the magnetic susceptibility,

– (C) is the Curie-Weiss constant,

– (T) is the absolute temperature,

– (T_c) is the Curie temperature for ferromagnets or the Néel temperature for antiferromagnets.

This law is valid above the Curie or Néel temperature, where these materials undergo a phase transition from a ferromagnetic or antiferromagnetic ordered state to a paramagnetic disordered state.

Explanation: Curie-Weiss law is given by χe = εr -1 = C/(T-θ), where C is the curie
constant and θ is the characteristic temperature which is usually a few degrees higher
than the curie temperature for ferromagnetic materials.
