Abstract
The crystalline garnet Mn3Fe2Si3O12 and an amorphous phase of the same nominal composition are synthesized at high pressure. The magnetic properties of the two forms are reported. Both phases order antiferromagnetically. The crystalline phase exhibits a Curie-Weiss theta of â37.2â¯K, with a sharp ordering transition at 12â¯K. The glassy phase exhibits a larger antiferromagnetic Curie-Weiss theta, of â89.7â¯K, with a broad ordering transition observed at 2.5â¯K. The amorphous phase shows a much higher degree of magnetic frustration than the crystalline phase; it exhibits spin-glass behavior and is determined to have an actual composition of Mn3Fe2Si3O13.
