Abstract

original image

Gut in Form: α-Fe2O3-Tetrakaidekaeder (siehe Bild, links) und abgeschrägte α-Fe2O3-Parallelepipede (rechts) mit exponierten hochindizierten Flächen wurden in hohen Ausbeuten erhalten. Die magnetischen Eigenschaften beider Proben unterscheiden sich, offenbar aufgrund ihrer unterschiedlichen Formen und hochindizierten Flächen.
