    Notes: We present results on sound wave propagation in pulsed fields up to 50 T for CsCuCl3 and (VO)2P2O7. Sound velocity and attenuation exhibit anomalies at the field induced spin transitions at low temperatures. In CsCuCl3 we observe step-like anomalies in sound velocity and pronounced peaks in attenuation at the saturation field (34 T at 1.5 K) and broader anomalies at the commensurate-incommensurate transition (14–17 T). In (VO)2P2O7 we observe a strong anomaly at the critical field when the lowest triplet branch crosses the singlet ground state (27 T at 1.6 K). All these experiments give important information on the spin state in high magnetic fields of these low dimensional spin systems and on the spin-phonon coupling. © 2000 American Institute of Physics.

    Notes: Abstract: We present the temperature dependence of elastic modes of Fe3-xZnxO4 with x = 0, x = 0.02 and x = 0.032. The c44 shear modes show a pronounced softening which can be normalized to a common behavior for all these substances. We can explain the softening with a bilinear coupling of the elastic strain to an order parameter linked to charge ordering processes. The other elastic modes (c11, c12 and the bulk modulus) do not show any softening. We present a symmetry analysis for the charge ordering model.
