Ising exchange interaction in lanthanides and actinides KU Leuven
© 2015 IOP Publishing Ltd and Deutsche Physikalische Gesellschaft. The Ising exchange interaction is a limiting case of strong exchange anisotropy and represents a key property of many magnetic materials. Here we find the necessary and sufficient conditions to achieve Ising exchange interaction for metal sites with unquenched orbital moments. Contrary to current views, the rules established here narrow much the range of lanthanide and actinide ...
