Abstract

In order to investigate the dependence of the particle size on the cation distribution in the spinel structure, Mossbauer spectra were taken in the presence of an external magnetic field f3r the magnetic nanoparticles prepared by using a microemulsion method. The crystals are found to have a cubic structure. The results show that as the particle sizes decrease, $Fe^{3+}$ ions migrate from the octahedral site to tetrahedral site.

입자의 크기에 대한 스피넬 구조의 양이온 분포의 의존성을 조사하기 위하여 마이크로 에멀젼법으로 합성된 자성 나노입자에 대한 외부 자기장 하에서의 뫼스바우어 분광 실험을 하였다. 제조된 입자의 결정구조는 입방 스피넬 구조이었으며, 입자의 크기가 작아짐에 따라 $Fe^{3+}$이온이 팔면체 자리에서 사면체 자리로 이동하는 것이 확인되었다.
