Magnetic susceptibility of Cd_{1-x}Fe_{x}Te_{1-y}Se_{y} was found to consist of Van Vleck term (characteristic for the Fe^{2+} centers in tetrahedral crystal symmetry) and temperature-dependent contribution. The occurrence of the latter indicates an existence of additional magnetic moments. We ascribe their origin to the modification of the Fe^{2+} energy level spectrum induced by mixed Te-Se anion environment.
