AC Field-driven orientational crossover and energy dissipation in suspended magnetic nanoparticles
Iago López-Vázquez, Siraj Ul Haq, Kazuya Okada +4
By combining the Landau--Lifshitz--Gilbert equation with Brownian rotational dynamics of magnetic nanoparticles (MNPs), we theoretically investigate the role of particle rotation t…
Including nanoparticle shape into macrospin models
Iago López-Vázquez, Ãscar Iglesias, David Serantes
We investigate the feasibility of the macrospin approximation to account for the actual shape of soft magnetic nanoparticles (MNPs) with realistic geometries. Specifically focusing…
Tuning field amplitude to minimise heat-loss variability in magnetic hyperthermia
Necda Ãam, Iago López-Vázquez, Ãscar Iglesias +1
In this work, we theoretically investigate how shape-induced anisotropy dispersion and magnetic field amplitude jointly control both the magnitude and heterogeneity of heating in m…
Role of nanoparticle shape on the critical size for quasi-uniform ordering: from spheres to cubes through superballs
Iago López-Vázquez, David Serantes, Ãscar Iglesias
The equilibrium states of single-domain magnetite nanoparticles (NPs) result from a subtle interplay between size, geometry, and magnetocrystalline anisotropy. In this work, we pre…
