Magnetic and electric characterizations of sol–gel-derived NaFe(WO4)2 rods

Antiferromagnetism of Double Molybdate LiFe(MoO4)2

“…The inclusion of Li ion at A site make them suitable to be used in lithium-ion batteries as anode materials, while the W/Mo can provide a relative large spin-orbit coupling considering its 4d/5d orbitals 1,[6][7][8][9] . Most importantly, the B-site ions with narrow bands can provide other applicable physical properties, such as magnetism and luminescence [10][11][12][13][14][15] .…”

“…Double tungstates and molybdates with the chemical formula A I B III (MO 4 ) 2 form a big family of transition metal oxides, where A is an alkali metal; B is a trivalent cation such as Bi 3+ , In 3+ , or Fe 3+ or a rare earth, Sm 3+ or Eu 3+ ; and M represents W 6+ or Mo 6+ . − The combinations of three categories of metal ions make this family full of varieties in physics and functionality.
