Dimensional Effects and Intercluster Interactions in Nanosystems

摘要

Magnetic, structural-dynamic, and catalytic properties of nanocluster systems including both isolated and mutually interacting clusters of oxides of iron and other metals were studied. The influence of dimensional effects and intercluster interactions was discovered for nanosystems including metal oxides both with no carrier and in polymeric and carbon matrices. These effects were displayed in decrease in the critical temperature of magnetic phase and structural transitions, appearance of a critical cluster size for first-order magnetic phase transitions, change of the character of magnetic phase transitions, and change of atomic and cluster dynamics, as well as of adsorption and catalytic properties.
