Аннотация: The properties of Na (x) Li1-x FeGe2O6 (x = 0.1-0.9) solid solutions obtained via a solid-phase synthesis have been measured by X-ray diffraction, calorimetry, and magnetic method. The order-disorder transformations in low-dimensional Na (x) Li1-x FeGe2O6 (x = 0.1-0.9) spin systems with predominately antiferromagnetic exchange inteПоказать полностьюraction have been revealed in the low-temperature susceptibility dependences. The study of thermal and physical properties has confirmed that substituting the sodium ions with the lithium ones induces the first-order structural phase transitions of the displacement type which are characterized by a symmetry change in monoclinic crystals from high-temperature C2/c space group to low-temperature P2(1)/c space group.
