Pierre Curie discovered this relation, now known as Curie's law, by fitting data from experiment. It only holds for high temperatures and weak magnetic fields. As the ...
In magnetism, the Curie–Weiss law describes the magnetic susceptibility χ of a ferromagnet in the paramagnetic region above the Curie temperature: = where C is a material-specific Curie constant, T is the absolute temperature, and T C is the Curie temperature, both measured in kelvin.
Curie's law is valid under the commonly encountered conditions of low magnetization (μ B H ≲ k B T), but does not apply in the high-field/low-temperature regime where saturation of magnetization occurs (μ B H ≳ k B T) and magnetic dipoles are all aligned with the applied field. When the dipoles are aligned, increasing the external field ...

Pierre Curie's grandfather, Paul Curie (1799–1853), a doctor of medicine, was a committed Malthusian humanist and married Augustine Hofer, daughter of Jean Hofer and great-granddaughter of Jean-Henri Dollfus, great industrialists from Mulhouse in the second half of the 18th century and the first part of the 19th century.

Pierre Weiss was born in Mulhouse the 25 March 1865, where he was the first born of Émile Weiss and Ida Schlumberger. At the age of 5, Alsace was annexed to Germany. Weiss conducted his secondary studies at Mulhouse.
While some substances obey the Curie law, others obey the Curie-Weiss law. = T c is the Curie temperature. The Curie-Weiss law will apply only when the temperature is well above the Curie temperature. At temperatures below the Curie temperature the substance may become ferromagnetic. More complicated behaviour is observed with the heavier ...
