Abstract

The response of magnetic particles at different frequencies is important for different applications ranging from mobility magnetic particle imaging in the lower kHz range up to a few hundred kHz for applications like magnetic fluid hyperthermia. In addition, realistic particles have different magnetic anisotropies contributing to the observed response. In this work, the response of particles with mixed cubic and uniaxial anisotropy in the frequency range from 1 kHz to 1 MHz are simulated by solving the corresponding Langevin equations for the mechanical and magnetic rotation of the particles. It is shown that even small ratios of cubic to uniaxial anisotropy visibly influence the response of the particles.
