Abstract
We have measured the magnetic susceptibilities of a CuF/sub 2/ .center dot. 2H/sub 2/O sample by means of the SQUID(superconducting quantum interference device) at the magnetic fields of 0.5 T and 1 mT, in the temperature range 5-300 K. The sample was found to contain some nonmagnetic calcium and magnesium impurities by the elemental analysis. Our measurements differ from known results for pure Cu F/sub 2/ .center dot. 2H/sub 2/O and are well explained by the effect of the nonmagnetic impurities in our sample. The purity of our sample derived from the temperature dependence of the susceptibilities was compared with that from the elemental analysis.
