The neutron diffraction studies of a crystal structure of nafe(wxmo1-xo4)2 (x = 0.5; 0.75) at low temperature
The crystal structure of the double tungstates NaFe(W0.5Mo0.5O4)2 and NaFe(W0.75Mo0.25O4)2 has been studied by means of a neutron diffraction method in temperature range 5-24 K. No evidence for long range magnetic order was found in both compounds down to 5 K. The unit cell parameters, atomic coordi...
