Abstract We report on measurements of the magnetization of metal sinters made of different Ag powders with average (nominal) grain sizes of 40nm and 70nm at1.6K≤T≤250K and0≤B≤6T. Besides the dominating diamagnetism of Ag, the sinters show unexpected magnetic properties; e.g. once exposed to a magnetic field B, the sinters keep a permanent magnetic moment (in zero external field) which strongly depends on the magnitude of B. The possible impact of the unexpected magnetic properties of the Ag sinters on various experimental observations at very low temperatures, e.g. the magnetic field dependence of the thermal boundary resistance between an Ag sinter and3He at millikelvin temperatures is discussed.
