Polar and Magnetic Mn2FeMO6 (M=Nb, Ta) with LiNbO3type Structure: HighPressure Synthesis

Polar and Magnetic Mn2FeMO6 (M=Nb, Ta) with LiNbO3-type Structure: HighPressure Synthesis Polar LiNbO3-type magnetic oxides have been extended, for the first time, to the A2BB’O6 family. Mn 2+ 2Fe MO6 (M= Nb, Ta), synthesized at high pressure, adopt a polar structure, as demonstrated by electron diffraction and the second harmonic generation effect, and they have interesting magnetic properties.
