“…The monotonic increase of the transverse modes confirms the delocalization of the 4f electrons. Magnetic field effects on the longitudinal C 11 mode showed a remarkable effect with respect to the a axis while little dependencies were observed along b and c. By contrast, C 22 and C 33 show the same anisotropic behavior upon applied field [85].…”

Intermetallic compounds with the equiatomic composition CeTX that crystallize with the orthorhombic TiNiSi-type structure can be synthesized with electronrich transition metals (T) and X = Zn, Al, Ga, Si, Ge, Sn, As, Sb, and Bi. The present review focusses on the crystal chemistry and chemical bonding of these CeTX phases and on their physical properties, 119 Sn and 121 Sb Mössbauer spectra, high-pressure effects, hydrogenation reactions and the formation of solid solutions in order to elucidate structure-property relationships. This paper is the final one of a series of four reviews on equiatomic intermetallic cerium compounds [Part I

The elastic and magnetic properties of a single crystal of the bilayer manganese oxide ͑Pr 0.6 La 0.4 ͒ 1.2 Sr 1.8 Mn 2 O 7 have been investigated by means of ultrasonic and high-field magnetization measurements. Remarkable changes in the elastic constants C 11 , C 33 , C 44 , and C 66 as a function of temperature and magnetic field have been observed. In particular, a distinct elastic anomaly was observed at low temperatures and in magnetic fields when crossing the phase boundary between the paramagnetic insulating and the fieldinduced ferromagnetic metallic state. A pronounced elastic softening as a function of magnetic field ͑H͒ appears across the boundary of the low-temperature magnetic phase below around 40 K, accompanied by a distinct hysteresis. In the high-field region, however, these elastic constants exhibit a monotonic increase upon increasing the magnetic field. The high-field magnetization measurements characterizing the magnetic state point out a strong coupling between the elastic strain and the magnetic moment. The data can be described reasonably well considering a strong coupling between elastic strain and magnetic susceptibility m = ‫ץ‬M / ‫ץ‬H.

“…On the other hand, the elastic strain ε xy associated with the transverse C 44 mode couples to the quadrupolar moment O xy with 5 symmetry. The lowest order term of this perturbation can be described by [16][17][18][19][20][21][22][23] …”

We have performed ultrasonic measurements on the α-pyrochlore spin compounds R 2 Ti 2 O 7 , R = Tb, Dy, and Ho. A distinct dip appears around 80 K, especially in transverse modes (C 11 − C 12 )/2 and C 44 as a function of temperature in Dy 2 Ti 2 O 7 and Ho 2 Ti 2 O 7 compounds. This anomaly may correspond to a structural change detected by the temperature dependence of the permittivity and of the loss-angle tangent. No distinct anomaly was observed at lower temperatures in Dy 2 Ti 2 O 7 and Ho 2 Ti 2 O 7 compounds. On the other hand, a pronounced elastic softening toward low temperatures was observed in the temperature dependence of the principal elastic constants C 11 , (C 11 − C 12 )/2, and C 44 in Tb 2 Ti 2 O 7 . A detailed discussion of the highly distinct behavior among three compounds is given in terms of the magnitude of a splitting energy between the ground state and the excited one formed by the crystal-field effect. It seems that geometrically structural frustration prohibits the formation of a long-range quadrupolar ordering as well as a magnetic one, even if the coupling constant between quadrupolar moments is rather large enough in Tb 2 Ti 2 O 7 at low temperatures.
