Abstract

Motivated by the recent advances with magnetic nanoparticles, in this research we propose a new technique for their characterization based on the measurement of certain polarimetric parameters of the scattered light, such as the linear polarization degree when it is determined at a "right-angle" scattering configuration. We will show the sensitivity of its spectral evolution with the magnetic properties of the particle.

摘要

受近年来磁性纳米粒子研究进展的启发，本研究提出了一种基于测量散射光某些偏振参数的新方法来对其进行特性描述，例如在“直角”散射配置下确定的线性偏振度。我们将展示其光谱随粒子磁性能变化的灵敏度。
