Abstract
The magnetic susceptibilities of $^{3}\mathrm{He}$ films on $^{4}\mathrm{coated}$ sintered silver powder were measured with a superconducting quantum interference device magnetometer in the temperature range between about 1 and 10 mK. Even a monolayer of $^{4}\mathrm{He}$ was found to have a dramatic effect on the susceptibilities of $^{3}\mathrm{He}$ adsorbed on top of it. Two layers of $^{4}\mathrm{He}$ completely extinguished the anomalous magnetic susceptibility of $^{3}\mathrm{He}$, leaving only the Fermi-degenerated temperature-independent susceptibility.
