The susceptibility of a quasi-one-dimensional spin system for molecule-based ferromagnets;

This paper elaborates the basic concept of molecule ferromagnet, manufacture technology and its application.

Energy spectra of double-layer ferrimagnetic superlattices;

The results indicate that for both NaCl and CsCl structure ferrimagnets the results of spin wave spectra and mean values of spin vector in Z-direction are strongly different from that of the ferrimagnets with the nearest-neighbor interactions only.

A brief introduction to the main facets of the field is presented,and several recent topics,including intramolecular magnetic coupling and molecular magnetic engineering,molecular-based ferromagnets,single-molecular magnets,spin-transition complexes and magnetic coupling in biological systems,are briefly reviewed.
