We have measured the magnetic susceptibilities of single crystals of ${\mathrm{Cu}}_{1\ensuremath{-}x}{\mathrm{Zn}}_{x}{\mathrm{GeO}}_{3}$ with extremely low Zn concentration $(x)$ lower than $x=5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ at very low temperatures to investigate the spin-Peierls and antiferromagnetic transitions. The results show that the undoped ${\mathrm{CuGeO}}_{3}$ has no antiferromagnetic phase down to 12 mK and there exists an …
