Orbital degrees of freedom and ordering phenomena in a 4f system
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.
