摘要：

Unusual magnetic behavior of α-Fe2O3: Rice- (a) and cube-shaped (b) single-crystalline α-Fe2O3 nanostructures (see microstructure images) are obtained by a new hydrothermal reaction route. Different magnetic anisotropies are observed for the rice- and cube-shaped α-Fe2O3 nanocrystals. This behavior offers possibilities for technological applications of α-Fe 2O3 with magnetic properties tailored by shape-controlled synthesis. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co.
