- The magnetic ordering in $ErFe_{0.3}Ge_{2}$ and $ErNi_{0.65}Ge_{2}$ compounds crystallizing in the orthorhombic structure of the $CeNiSi_{2}$-type has been investigated by neutron diffraction and magnetic measurements. The Er magnetic moments have been found to order antiferromagnetically below 2.5 K in $ErFe_{0.3}Ge_{2}$ and 2.3 K in $ErNi_{0.65}Ge_{2}$. The magnetic structure of the former compound can be described by the propagation vector k = (0.044(1), 0, 0.384(1)). The Er magnetic moments are aligned along the a-axis and alternate with the sequence ++- in the unit cell. At 1.5 K they are equal to 5.9(1) $μ_{B}$. In contrast, the magnetic unit cell of $ErNi_{0.65}Ge_{2}$ has been established to be equal to the chemical one. The magnetic moments in this compound are arranged in a collinear manner pointing along the a-axis with the sequence +-+-. The Er moment value measured at 1.5 K is 2.90(8) $μ_{B}$.
