Phys. Rev. B 79, 233106 (2009) [4 pages]Electrical resistivity, high-resolution thermal expansion, and heat capacity measurements of the charge-density wave compound γ-Mo4O11Received 23 February 2009; revised 8 May 2009; published 18 June 2009 Electrical resistivity of γ-Mo4O11 single crystals was measured using the Montgomery method. The results show a much smaller anisotropy than previously reported. High-resolution linear thermal expansion measurements reveal strongly anisotropic behavior. Both electrical resistivity and thermal expansion measurements suggest that this material should be classified as quasi-two dimensional. The thermal expansion coefficients exhibit an anomaly due to the charge-density wave transition along the b and c axes at ∼100 K. © 2009 The American Physical Society URL:
