Journal ArticleDOI
Estimation of the effective magnetic anisotropy constant of multi-core based magnetic nanoparticles from the temperature dependence of the coercive field
Keiji Enpuku,Ahmed L. Elrefai,Ahmed L. Elrefai,Takashi Yoshida,Tamara Kahmann,Jing Zhong,Thilo Viereck,Frank Ludwig +7 more
TL;DR: In this article, the effective magnetic anisotropy constant (K) of magnetic nanoparticles (MNPs) was estimated from the temperature dependence of the coercive field Hc of the M-H curve for use in biosensing applications.
Journal ArticleDOI
Magnetic field dependence of the effective magnetic moment of multi-core nanoparticles
Tamara Kahmann,Frank Ludwig +1 more
TL;DR: In this article, the effect of the applied magnetic field on the effective magnetic moment of multi-core magnetic nanoparticles (MNPs) has been investigated in a multicell MNP system and the results showed that the magnetic moment depends on the size of individual crystallites, their packing density, core configuration and the interaction between them.
Journal ArticleDOI
The Dissociation Rate of Acetylacetonate Ligands Governs the Size of Ferrimagnetic Zinc Ferrite Nanocubes.
Aidin Lak,Tamara Kahmann,Simon J. Schaper,Jaroslava Obel,Frank Ludwig,Peter Müller-Buschbaum,Jan Lipfert +6 more
TL;DR: This method reduces the complexity of the thermal decomposition method by narrowing the synthesis parameter space to a single physical parameter and enables fabrication of highly magnetic and uniform zinc ferrite nanocubes over a broad size range.
Journal ArticleDOI
Determination of the effective anisotropy constant of magnetic nanoparticles – Comparison between two approaches
TL;DR: In this article, the Stoner-Wohlfarth model is used to determine the anisotropy field and the descending branch of the magnetic moment-vs-magnetic field (m-H) curve measured on immobilized magnetic nanoparticles.
Journal ArticleDOI
Effect of core size distribution on magnetic nanoparticle harmonics for thermometry
Zhongzhou Du,Yi Sun,Oji Higashi,Yuki Noguchi,Keiji Enpuku,Sebastian Draack,Klaas Julian Janssen,Tamara Kahmann,Jing Zhong,Thilo Viereck,Frank Ludwig,Takashi Yoshida +11 more
TL;DR: In this paper, the effect of core size distribution on the performance of a magnetic nanoparticle thermometer (MNPT) in circumstances when Neel relaxation dominates the dynamic behavior of particles was investigated.
