HfZn2 is known to be an exchange enhanced paramagnet, with a strongly temperature dependent susceptibility. In a new study, a sample of HfZn2 has been prepared, which is even more strongly enhanced and hence closer to ordering ferromagnetically than found in a previous study. The values of the electronic contribution to the specific heat, the magnetic susceptibility at T = 0, χ(0) and the Stoner exchange enhancement factor S = 1/| N(EF)I-1| have all been found to increase substantially compared to earlier results.
