“…The basic nuclear moment data for the different ytterbium isotopes ( 170 Yb, 171 Yb, 172 Yb, 174 Yb, 176 Yb) have been summarized by Stevens and Dunlap; however, 170 Yb is the usually studied isotope. Its basic Mössbauer spectroscopic characteristics are: I e = 2 (nuclear spin operator in the excited state); I g = 0 (nuclear spin quantum number in the ground state); transition energy of 84.25 keV; TmB 12 as the usual source (typically 20 mCi) with a half-life of 130 d; and natural line width of 2.03 mm s –1 . ,− …”

The present review summarizes important aspects of the crystal chemistry of ytterbium-based intermetallic compounds along with a selection of their outstanding physical properties. These originate in many cases from the ytterbium valence. Different valence states are possible here, divalent (4f 14 ), intermediate-valent, or trivalent (4f 13 ) ytterbium, resulting in simple diamagnetic, Pauli or Curie−Weiss paramagnetic, or valence fluctuating behavior. Especially, some of the Yb 3+ intermetallics have gained deep interest due to their Kondo or heavy Fermion ground states. We have summarized their property investigations using magnetic and transport measurements, specific heat data, NMR, ESR, and Mossbauer spectroscopy, elastic and inelastic neutron scattering, and XAS data as well as detailed thermoelectric measurements.
