Abstract
NaFeGe2O6 is a one of the representatives of the pyroxene family with the general formula Me1+Me3+Si(Ge)2O6 (Me1+- monovalent metal cation, Me3+-3-d transition metal cation), which regained strong interest in spintronics as a new class of multiferroic materials and in solid-state physics as a quasi-low-dimensional insulating system. The sodium iron germanate NaFeGe2O6 powder was synthesized at 800°, 900° C for 4 days from the stoichiometric mixture of Na2CO3, Fe2O3, GeO2 by solid state reaction after several cycles of regrinding. Using neutron powder diffraction the magnetic order below TN ≈ 13 K was found and the magnetic structure has been determined. It is incommensurate and consists of antiferromagnetically coupled Fe3+ pairs with helical modulation within the a-c plane of the crystal lattice.
