Abstract

The non-linear signal generation in Magnetic Particle Imaging (MPI) using magnetic nanoparticles as tracer materi- als is still not fully explained and a far-reaching research area. Magnetic Particle Spectroscopy (MPS) was developed to investigate the particle behavior at high externally applied magnetic field strengths and to derive mathematical models which describe the physical processes in MPI in detail. A new MPS setup was built which allows measure- ments between −13 degree Celcius and +114 degree Celcius in order to investigate the temperature dependence of the harmonics spectra. Temperature-dependent MPS measurements of diluted FeraSpin XL, either as suspension or freeze-dried in a mannitol matrix, using the new setup are shown and exemplarily discussed.
