| Abstract: | Magnetic properties of oxygen pair clusters are investigated theoretically for different geometries of clusters which can be realized by doping molecular cryomatrices with oxygen. Anomalous temperature and pressure behavior of the magnetic susceptibility, magnetic heat capacity and magnetic entropy is predicted. It is shown that the low-temperature magnetic susceptibility of these solid solutions is very sensitive to the orientational structure of impurity oxygen clusters, which makes it possible to use the susceptibility data for studying structural and dynamics properties of the host lattice, including high-pressure phases of simple molecular crystals. |
