Abstract
New precise data of the $\Lambda^0$ polarization are obtained in the EXCHARM experiment at the Serpukhov accelerator. The $\Lambda^0$s have been produced in nC interactions in the neutron energy interval 40-70GeV and detected in the kinematic range of $0.1\lesssim x_{\mathrm {F}}
\lesssim 0.6$and $0.2\le p_{\mathrm {t}} \le 1.2$GeV/c. The obtained results are compared with other measurements in the pp and pA interactions.
