AC Magnetic Susceptibility of Magnetic Nanoparticles Measured Under DC Bias Magnetic Field

نویسندگان

چکیده

The magnetization dynamics of magnetic nanoparticles are essential for the medical applications hyperthermia and particle imaging. In this paper, we clarified AC susceptibility superparamagnetic their frequency dependence. We measured under an applied DC bias field. dependence was clearly observed. experimentally obtained characteristics samples with different effective core diameters on intensity field agreed theory assuming a simple model. sample comprising wide distribution exhibited than magnetically fractionated narrower diameter distribution.

Quantitatively probing the magnetic behavior of individual nanoparticles by an AC field-modulated magnetic force microscopy

Despite decades of advances in magnetic imaging, obtaining direct, quantitative information with nanometer scale spatial resolution remains an outstanding challenge. Current approaches, for example, Hall micromagnetometer and nitrogen-vacancy magnetometer, are limited by highly complex experimental apparatus and a dedicated sample preparation process. Here we present a new AC field-modulated ma...

Size dependent heat generation of magnetite nanoparticles under AC magnetic field for cancer therapy

BACKGROUND We have developed magnetic cationic liposomes (MCLs) that contained magnetic nanoparticles as heating mediator for applying them to local hyperthermia. The heating performance of the MCLs is significantly affected by the property of the incorporated magnetite nanoparticles. We estimated heating capacity of magnetite nanoparticles by measuring its specific absorption rate (SAR) agains...
