Journal ArticleDOI
Characterization of Néel and Brownian Relaxations Isolated from Complex Dynamics Influenced by Dipole Interactions in Magnetic Nanoparticles
Satoshi Ota,Yasushi Takemura +1 more
TL;DR: In this article, a fast-responding pulse field was used to evaluate the Neel and Brownian regimes of magnetic relaxations, and the dependence of the two-step magnetization response of magnetic nanoparticles dispersed in a fluid in the Brownian regime occurred after Neel regime.
Journal ArticleDOI
Enhanced specific loss power from Resovist® achieved by aligning magnetic easy axes of nanoparticles for hyperthermia
TL;DR: In this paper, the specific loss powers (SLP) of magnetic nanoparticles (MNPs) were calculated based on dynamic hysteresis measurements, where the magnetic field was applied either parallel or perpendicular to the nanoparticle orientation.
Journal ArticleDOI
Dipole-dipole interaction and its concentration dependence of magnetic fluid evaluated by alternating current hysteresis measurement
TL;DR: In this article, water-dispersed MNPs of different concentrations and MNPs fixed with an epoxy bond were measured, and intrinsic loss power (ILP) was estimated from the areas of the ac hysteresis loops.
Journal ArticleDOI
Rotation of Magnetization Derived from Brownian Relaxation in Magnetic Fluids of Different Viscosity Evaluated by Dynamic Hysteresis Measurements over a Wide Frequency Range.
TL;DR: It is revealed that Brownian and Néel relaxations coexist and thatBrownian relaxation can occur after NÉel relaxation despite having a longer relaxation time.
Journal ArticleDOI
Effects of size and anisotropy of magnetic nanoparticles associated with dynamics of easy axis for magnetic particle imaging
Satoshi Ota,Yuki Matsugi,Takeru Nakamura,Ryoji Takeda,Yasushi Takemura,Ichiro Kato,Satoshi Nohara,Teruyoshi Sasayama,Takashi Yoshida,Keiji Enpuku +9 more
TL;DR: In this article, the effect of magnetic particle structures on the magnetization harmonics was investigated and the dependence of the harmonics on the size and anisotropy of different structures was investigated.
