FTP, name this man who discovered radium and polonium with his wife.
The ratio between two material-dependent quantities named for this man is given by the Weiss coefficient. This man and his older brother discovered a phenomenon exhibited by 20 of the 21 point groups which lack a center of inversion. That linear phenomenon is similar to a universal quadratic phenomenon representing the failure of Hooke's law in describing the changes in interionic distances with applied field, an effect known as electrostriction. His law gives an inverse relationship between temperature and magnetization for paramagnetic materials. Ferromagnetic materials become paramagnetic above a temperature known as his point.
