The de Haas-van Alphen effect of pure zinc crystal was investigated at temperatures ranging from 63°to 1.3°K by means of a torsion magnetometer. In the magnetic field less than 16 kilo-oersted and at the temperatures 4.2°K and above, a remarkable periodic variation of magnetic susceptibility was found with the intensity of magnetic field and it is here referred to as the long-period effect. While in the field higher than 19 kilo-oersted and at temperatures from 4.2°to 1.3°K, it was observed that a shorter-period and smaller-amplitude effect, which is accompanied by some complicated beat structures, is superposed on the high field extension of the long-period effect just cited. From the analysis of the long-period effect, we obtained the next de Haas-van Alphen parameters : E_<0l>=5.5×10^<-14> erg, m_<1l>/m_0=5.4×10^<-3>, m_<3l>/m_0=2.7×10^<-1>, T_<Dl>=400°K, n_l=1.2×10^<-6>atom^<-1>; and from the analysis of the short-period effect, we got : E_<0s>=7.9×10^<-14> erg, m_<1s>/m_0=1.6×10^<-1>, m_<3s>/m_0=8.3×10^<-2>, T_<Ds>=570°K, n_s=3×10^<-5> atom^<-1>.
