In contrast with this behavior, diamagnetic materials are repelled by magnetic fields … See more Constituent atoms or molecules of paramagnetic materials have permanent magnetic moments (dipoles), even in the absence of an applied field. The permanent moment generally is due to the spin of unpaired … See more Materials that are called "paramagnets" are most often those that exhibit, at least over an appreciable temperature range, magnetic susceptibilities that adhere to the Curie or Curie–Weiss laws. In principle any system that contains atoms, ions, or molecules with … See more • Media related to Paramagnetism at Wikimedia Commons • Magnetism: Models and Mechanisms in E. Pavarini, E.
