Substances with positive magnetic susceptibilites are said to be paramagnetic, which implies that they will have induced magnetic moments in the direction of an applied magnetic field. A ferromagnet, on the other hand, has a spontaneous magnetic...

The Curie point (Tc), or Curie temperature, is a term in physics and materials science, named after Pierre Curie (1859-1906), and refers to a characteristic property of a ferromagnetic or piezoelectric...
