Magnetism magnetic properties, cathode

Magnetic properties of iron nanocrystals nested in carbon cages, which grew on the cathode deposit, have been studied by Fliura el al.[29]. Magnetization (M-H) curves showed that the coercive force. He, of... 

Later experiments by J. J. Thomson, an English scientist, demonstrated the electrical and magnetic properties of cathode rays (Figure 2.5). The rays were deflected toward the positive electrode of an external electric field. Because opposite charges attract, this indicates the negative character of the rays. Similar experiments with an external magnetic field showed a deflection as well hence these cathode rays also have magnetic properties. 

The most complete phase studies have been carried out on LiF-RFs and NaF-RFs systems in 1960-1970. This interest was mainly based on their importance in Molten-Salt Reactor Programs (e.g. Thoma and co-workers at Oak Ridge National Laboratory, USA Keller and Schmutz of the Society of Nuclear Research in Karlsruhe, West Germany). Furthermore, some of the intermediate phases are suitable as host lattices for lasers, e.g. A(R R )F4, and up-conversion materials, e.g. A(R R R")F4. Magnetic properties of ARF4 phases have also been studied and are reviewed in the Gmelin Handbook (1976). A few NaRF4 phases show fluorescence after irradiation with cathodic rays.
