Abstract

Preliminary data for the heat capacity of 3He in 3He-4He mixture films on a Nuclepore substrate are reported over the temperature range 90≤T≤165 mK, for 3He coverages between 0.05 and 1.7 bulk-density atomic layers, and a 4He film thickness of 4.33 bulk-density atomic layers. In this two-dimensional Fermi liquid system, a step structure appears in the specific heat as a function of 3He coverage, similar to the step previously observed in the magnetization.
