Progress in High-field EPR

In view of the increased availability of HFEPR spectrometers it is not surprising that the number of papers containing at least a section on HFEPR has continued to increase since our last survey. Work on biological systems has always been a feature of HFEPR, and since the last review there has also been an increasing number of studies of new materials in which many magnetic atoms are closely coupled to form a molecular cluster. We have divided the review into three main sections. The first section covers materials research, the second biological applications and the third surveys recent advances in instrumentation. 

A number of reviews of aspects of HFEPR have been produced recently including applications to molecular magnetic clusters, catalysis and antiferromagnetic (AFM) and ferromagnetic (FM) materials, particularly those with lowdimensional spin interactions.  

As more and more complicated materials are synthesized it has become clear that many techniques should be applied to the same sample in order to characterize the system adequately. One technique that is complementary to HFEPR,

In some cases the values of D and E given in a paper were derived from a spectrum fitting analysis including higher-order terms. We shall indicate this by D. The original papers should be consulted for the higher-order terms. (See also the remarks in Section 2.7.)]
