Magnetic Nanoparticles in Magnetic Fluids
Magnetic fluids are stable colloidal systems of fine single-domain magnetic particles (for example Fe3O4, γ-Fe2O3, Co, MnFe2O4, etc.) that are suspended in liquid carrier such as water, mineral oil, damping oil, paraffin, kerosene and so on. The properties of magnetic fluids are well controlled by external magnetic field that gives broad possibilities for technical and biomedical applications. ...
متن کاملCharacterisation of magnetic fluids
One method suitable for the accurate characterisation of magnetic fluids is by the measurement of the frequency-dependent, complex susceptibility, χ(ω) = χ′(ω) − iχ′′(ω). Such measurements enable data on, relaxation mechanisms, ferromagnetic resonance, stochastic resonance, non-linear properties, magnetic losses and the signal-to-noise ratio (SNR) of these colloidal nano-particle systems to be ...
متن کاملVisual Simulation of Magnetic Fluids
In this paper, we focus on simulation of magnetic fluids. Magnetic fluids behave as both fluids and as magnetic bodies, and these characteristics allow them to generate ‘spike-like’ shapes along a magnetic field. Magnetic fluids are popular materials for use in works of art. Our goal is to simulate such works of art. In the field of electromagnetic hydrodynamics, many methods have also been pro...
متن کاملMagnetic turbulence in compressible fluids
We present high resolution numerical simulations of compressible magnetohydrodynamic (MHD) turbulence. We concentrate on studies of spectra and anisotropy of velocity and density. We describe a technique of separating different magnetohydrodynamic (MHD) modes (slow, fast and Alfven) and apply it to our simulations. For the mildly supersonic case, velocity and density show anisotropy. However, f...
متن کاملOn the dynamics of magnetic fluids in magnetic resonance imaging
The hydrodynamics of magnetic fluids, often termed ferrofluids, has been an active area of research since the mid 1960s. However, it is only in the past twenty years that these fluids have begun to be used in magnetic resonance imaging (MRI) where they have found application as contrast agents, improving the contrast to noise ratio of the received MR intensity. The major goal of this work was t...
