Numerical Study on the Magnetization Characteristics of Chainlike Magnetic Nanoparticles
TL;DR: In this article , the authors investigated chain-like magnetic nanoparticles (CMNPs) with a dipole-dipole interaction in which individual nanoparticles are connected to form a chainlike structure and numerically analyzed the ac magnetization characteristics of the CMNP and the single-core MNP using the Landau-Lifshitzitz-Gilbert equation.

Heating magnetic fluid with alternating magnetic field
TL;DR: In this paper, the authors developed analytical relationships and computations of power dissipation in magnetic fluid (ferrofluid) subjected to alternating magnetic field and showed that the dissipation results from the orientational relaxation of particles having thermal fluctuations in a viscous medium.
