We have demagnetized 8.3mmol Auln 2 and measured its heat capacity C at 2mTs B~II5mT and 40/~K~TslmK. We get C~B2/T e with B2=Bext2+blnt 2 at "high" temperatures. At the lowest temperatures C is strongly enhanced above this Schottky behaviour. In fields Bz47mT we observe a maximum in C. In smaller
## A metallic TI sample of 99.998% nominal purity was precooled to 15 mK in a field of 6 T, During demagnetization unexpected and so far unexplained losses in the entropy reduction are observed; demagnetizing to O. 1 T yields a final temperature around 0.5 mK only, and demagnetization to below 75 mT
