Abstract [1] Magnetic states of systems of interacting heterogeneous particles modeling a fer-romagnetic rock are theoretically studied. Main attention is given to such important characteristics of the systems as the spontaneous magnetization, the critical field of an irreversible change in the grain magnetic moment, and the distribution of interaction fields.

2015-3-18 · The magnetic properties of small ferromagnetic particles with diameters typically about 10 nm are governed by two characteristic features. Namely, the single-domain magnetic structure and the enhanced coercivity. The former occurs be-cause the size of the system is smaller than the exchange correlation length and the latter is a consequence of ...

We present ferromagnetic resonance (FMR) and magnetic properties of single domain Y3Fe5O12 (YIG) nanoparticles with an average size of 60 nm. The saturation magnetization shows a diminution of practically 1 of the bulk magnetization due to the surface/volume contribution. The coercive force vs. temperature indicates that the particles are single magnetic domains in the

The magnetic fabric of rocks and sediments is most commonly characterized in terms of the anisotropy of low-field magnetic susceptibility (AMS). However, alternative methods based on remanent magnetization (measured in the absence of a magnetic field) rather than induced magnetization (measured in the applied field) have distinct advantages for certain geological

Today, it is well known that small airborne particles are very harmful to human health. For the first time in Hawaii we have conducted an environmental pilot study of fine magnetic particles on the island of Oahu, Hawaii, of particulate matter (PM) PM = 60, PM = 10, and PM = 2.5. In order to do a rock magnetic characterization we have performed low field susceptibility vs. temperature [k
