(\theta\) from Curie-Weiss fit, Curie temperature \(T_C\) from Arrot ... WebThis is known as the Curie-Weiss Law: χ = C/(T – θ), where θ is a measure of ferromagnetic or antiferromagnetic interactions at low temperature. There are many ways to measure the magnetic susceptibility. The classic technique is Faraday's, where the mass of a sample is measured in the absence and presence of a magnetic field.
