| Abstract: | New metal oxide pyroxene compound NaVGe2O6 containing isolated edge-sharing VO6 (S=1) chains undergoes transition into a long-range antiferromagnetic state at T N =16 K. The broad maximum in the temperature dependence of magnetic susceptibility at T M =26 K indicates the low-dimensional character of the magnetic subsystem. Even though the antiferromagnetic ordering is accompanied by a sharp peak of specific heat, significant magnetic entropy is released above the Néel temperature. |
