摘要：

Magnetic gamma-Fe2O3 (maghemite) grains have been incorporated in solid silica gel matrices under a static magnetic field which orientated at the magnetic particles during gelation. When the field is switched off, dried gel samples exhibit permanent birefringence corresponding to the locking of oriented magnetic particles.
