An ""ac"" or temperature modulation method allowed the use of very small single crystal samples. The heat capacity peak for our best sample is rounded in a range of lO at the Curie point (Tc ). Outside this region, good power law fits are obtained fora range of values of the critical exponents alpha (above Tc) and alpha' (below Tc )' the choice of which depends on the choice of Tc The entire set of data, including that in the rounded region, fits an expression derived from a simple macroscopic model of rounding. The Tc specified by this fit makes alpha = -.09 +/- .05 and alpha = -.32 +/- .05. Our results on Curie point and rounding are in disagreement with recent conjectures of Cadieu and Douglass for gadoliniumo" Submitted by Carolyn Mead (cmead2@illinois.edu) on 2011-07-13T19:00:08Z No. of bitstreams: 1 1969_lewis.pdf: 1601038 bytes, checksum: a18c7b6ebb3498ca5bcec67c6ed1a088 (MD5) Made available in DSpace on 2011-07-13T19:00:08Z (GMT).
