INVESTIGATION OF THE DYNAMIC PROPERTIES OF PHASE TRANSITIONS OF ORDERED MAGNETIC STATES.
Abstract
Research is reported on the properties of magnetic phase transitions. A survey was made of experiments were suggested which should be useful in their study: and several of these experiments were performed on the spin flop transition in antiferromagnetic CuCl2.2H2O. The components were measured of the susceptibility tensor relating to the perpendicular magnetization and obtained data in approximate agreement with a theoretical analysis based on the molecular field approximation. Research is reported on the optical properties of transition metal ions in crystalline solids. The spectrum of heavily doped ruby was and found narrow absorption bands in the ultra violet, which are shown to be cooperative absorption by pairs of Cr(3+) ions. The fluorescent spectrum of heavily doped ruby, the excitation spectrum of chromium doped spinels, and the absorption by chromium ions in the metastable state in ruby were studied.
