Orbital degrees of freedom and ordering phenomena in a 4f system. Amara, M., Luca, S., E., Galéra, R., M., Aviani, I., & Berar, J., F. Journal of Solid State Chemistry, 171(1-2):69-75, 3, 2003.
Website abstract bibtex Due to orbital degeneracy, a 4f electronic shell has the ability to distort when influenced by an electrostatic, magnetic or collective intersite field. In case of collective phenomena, the 4f asphericity which develops may result in a strain mode and/or introduce a new charge periodicity. The first is accessible via dilatometric techniques whereas the second needs a microscopic probe, X-rays, to be detected. To illustrate the efficiency of these techniques for sensing the 4f asphericity, the study of NdMg's collinear and multiaxial phases is introduced. © 2003 Elsevier Science (USA). All rights reserved.
