摘要

通过线性二色性测量，研究了氧化铁磁性纳米粒子（MNPs）在干燥和水分散样品中的磁性取向。当分散体中的原生 MNPs 形成磁矩比原生粒子大十倍左右的团聚体时，就会观察到 MNPs 的地磁取向。

Linear Dichroism Measurement of Geomagnetic Orientation of Magnetic Nanoparticles

The magnetic orientation of iron oxide magnetic nanoparticles (MNPs) in the dried and aqueous dispersion samples was investigated under weak magnetic fields down to the geomagnetic field by the linear dichroism measurements. The geomagnetic orientation of MNPs was observed when the primary MNPs in dispersions made the agglomerates with a magnetic moment about ten times larger than that of the primary particle.

期刊介绍： The Bulletin of the Chemical Society of Japan (BCSJ) is devoted to the publication of scientific research papers in the fields of Theoretical and Physical Chemistry, Analytical and Inorganic Chemistry, Organic and Biological Chemistry, and Applied and Materials Chemistry. BCSJ appears as a monthly journal online and in advance with three kinds of papers (Accounts, Articles, and Short Articles) describing original research. The purpose of BCSJ is to select and publish the most important papers with the broadest significance to the chemistry community in general. The Chemical Society of Japan hopes all visitors will notice the usefulness of our journal and the abundance of topics, and welcomes more submissions from scientists all over the world.
