摘要：

Formation of a long-range magnetic order is observed at low temperatures in NaCrSi2O6 and NaCrGe2O6 quasi-one-dimensional metal oxide compounds with a pyroxene structure. The first of these compounds, NaCrSi2O6, is an antiferromagnet with the Neel temperature T-N = 3 K, while the second, NaCrGe2O6, is a ferromagnet with the Curie temperature T-C = 6 K. From the measurements of magnetization and specific heat of these compounds, the main parameters of their magnetic subsystems are determined. In NaCrSi2O6, a spin-flip transition is observed. A change in the type of magnetic order that accompanies the replacement of Si by Ge can be attributed to a change in the parameters of the competing direct antiferromagnetic Cr-Cr and indirect ferromagnetic Cr-O-Cr interactions in isolated chains of CrO6 octahedra.
