Abstract
The structural cooperative Jahn-Teller phase transformation in TmAsO4 has been studied using gamma-ray diffraction. Precise measurements of the critical exponent, β, confirms the earlier reported classical value β = 0.50±.03. Precurser effects in the mosaic structure of the sample are observed as TD is approached from above.
