✦ Synopsis

We have used electrical resistivity and X-ray diffraction measurements to study SmTe2_ x (x ~0.1). The crystal structure is highly two-dimensional, but no evidence was found at room temperature for either charge density wave or ordered defect structures. Unlike the previously studied Sm polytellurides, the electrical resistivity of SmTel 9 is insulating, but displays a similar large electronic anisotropy.

Acoustic emission experiments have been performed on V 2 O 3 undergoing the metal-antiferromagnetic insulator transition near 150 K. The release of stress in the transition generates acoustic pulses which change on repeated thermal cycling. The observations are consistent with formation of nuclei of
