Lanthanide inelastic neutron scattering

In the study of lanthanide magnetism, neutron scattering (both elastic and inelastic) has played a seminal role in elucidating the complex nature of the magnetic interactions, and thus much of the discussion here will focus on results obtained by these techniques and how they relate to those observed by more conventional bulk experimental tools. 

In this review, we have attempted to survey what has been learned so far about lanthanide magnetism from both elastic and inelastic neutron scattering experiments. In a field as vast as this, there have inevitably had to be several omissions. Thus, we have had to omit discussions of critical scattering from lanthanide systems, of the very interesting studies of cooperative Jahn-Teller effects in some rare earth compounds, of measurements of the phonon spectra of these systems, and of a large number of neutron diffraction studies of many rare earth compounds other than those described in section 3.5. 

Chapter 200, by Peter M. Allenspach and M. Brian Maple, reviews some aspects of the low-temperature heat capacity of the ceramic oxide superconductors. These measurements yield valuable information about the electronic, lattice, magnetic, crystalline electric field and hyperfine nature of the various rare-earth cuprate materials, and in that respect compliment other physical property studies, such as neutron diffraction, inelastic neutron scattering, and various spectroscopic measurements. The authors review the heat-capacity properties of the stoichiometric RBaCu307 compoimds and oxygen-deficient materials, and show that there are significant differences. The heat capacities of other lanthanide cuprates, such as RBa2Cu40g and R2B4CU7O14+X, are also discussed.
