Abstract

Abstract The almandite (3FeO, Al 2O 3, 3SiO 2) was synthesized under 25 Kbars at 925°C. It has the grenat structure with a = 11.506 A ̊ and exhibits antiferromagnetic with a Neel temperature of 12K. It is like the natural ore without the impurities. There is no structural correlation with the amorphous compound except the antiferromagnetic interactions between Fe 2+ first neighbors.
