Abstract
Transport and specific heat measurements on hydrothermally grown single crystals reveal the formation of a heavy-mass Fermi liquid in the spinel, below a coherence temperature of . A few observations which illustrate the uniqueness of this spinel are discussed in connection with the origin of the heavy mass, such as the anomalous absence of resistivity saturation above and the close proximity to a spin glass phase where the influence of the magnetic frustration is evident.
