Magnetic particle–particle interaction in frozen magnetic fluids
Journal of Applied Physics, 1996Magnetic resonance is used to study magnetic dipole particle–particle interaction in ionic water-based iron-manganese magnetic fluids. A set of six samples having particle concentration running from 1.2×1016 to 6.3×1016 particles/cm3 were frozen below room temperature and analyzed in the range of 100–250 K.

Two-Dimensional Magnetic Particles
Science, 1998Single two-dimensional (2D) atomically thick magnetic particles of cobalt and iron with variable size and shape were fabricated by combining a mask technique with standard molecular beam epitaxy. Reduction of the lateral size of in-plane magnetized 2D cobalt films down to about 100 nanometers did not essentially modify their magnetic properties ...

Magnetic Particle Imaging (MPI)
RöFo - Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren, 2011Magnetic particle imaging (MPI) displays the spatial distribution and concentration of superparamagnetic iron oxides (SPIOs). It is a quantitative, tomographic imaging method with high temporal and spatial resolution and allows work with high sensitivity yet without ionizing radiation. Thus, it may be a very promising tool for medical imaging.

Narrowband Magnetic Particle Imaging
IEEE Transactions on Medical Imaging, 2009The magnetic particle imaging (MPI) method directly images the magnetization of super-paramagnetic iron oxide (SPIO) nanoparticles, which are contrast agents commonly used in magnetic resonance imaging (MRI). MPI, as originally envisioned, requires a high-bandwidth receiver coil and preamplifier, which are difficult to optimally noise match. This paper

Water purification with magnetic particles
Environmental Monitoring and Assessment, 1991CSIRO (Commonwealth Scientific and Industrial Research Organization) has for some years carried out research into more efficient ways of purifying water and wastewater. More intensive processing has been achieved by the use of finely divided solid reagents which can be regenerated and reused.

Magnetization of single magnetic particles
Journal of Magnetism and Magnetic Materials, 1995Abstract We present the first magnetization measurements of single submicron (Co, CoZr, Ni) particles. As a detector we use a microbridge-dc-SQUID deposited onto or next to the sample. Sample and detector are patterned by electron-beam lithography. The dynamics and the temperature dependence of the magnetization reversal are studied.

A new type of flat-panel ambient-illuminated display is described. Images in this display are formed by magnetically controlling the orientations of small spherical multicolored magnetic particles. A demonstration model is shown and the possibility for application to television is studied.

Magnetic particle nanorheology
Colloid and Polymer Science, 2014We investigate the employment of AC susceptometry as a novel method to extract frequency- and scale-dependent rheological properties of soft materials. The approach makes use of the interrelation between the magnetic susceptibility of magnetically blocked tracer particles and the mechanical modulus of the matrix as experienced on the particle scale. We

We have fabricated ultrathin Co particles with various shapes, variable thicknesses δ (2 ML<δ<22 ML), and lateral size L ranging from 100 μm to ≈100 nm. We find that all particles are magnetized in-plane at room temperature and are in a single domain state, independently of shape and size—with some remarkable exceptions. We also find that
