Issues associated with the exposure of patients to strong, static magnetic fields during magnetic resonance imaging (MRI) are reviewed and discussed. The history of human exposure to magnetic fields is reviewed, and the contradictory nature of the literature regarding effects on human health is described. In the absence of ferromagnetic foreign bodies, there is no replicated scientific study sh...

Whereas dc measurements of magnetic susceptibility, χ, fail to distinguish between local and weak itinerant ferromagnets, radio-frequency (rf) measurements of χ in the ferromagnetic state show dramatic differences between the two. We present sensitive tunnel-diode resonator measurements of χ in the weak itinerant ferromagnet ZrZn2 at a frequency of 23 MHz. Below Curie temperature, TC ≈ 26 K, th...

Lake Qinghai is the largest lake in China and situated in an important climate-sensitive zone on the northeastern margin of the Tibetan Plateau, making it an ideal place to study the environmental evolution of the northwest China as well as the interplay between the Asian monsoon and the westerlies in the late Quaternary. In this study, detailed rock magnetic measurements were carried out on th...

Magnetic resonance imaging (MRI) and magnetic particle imaging (MPI) are powerful methods in the early diagnosis of diseases. Both imaging techniques utilize magnetic nanoparticles that have high magnetic susceptibility, strong saturation magnetization, and no coercivity. FeraSpinTM R and its fractionated products have been studied for their imaging performances; however, a detailed magnetic ch...

The geostatistics technique is widely used to identify the variability of soil attributes, although being expensive due large number samples that it requires. In this sense, magnetic susceptibility has been an alternative assess landscape variation, a fact can assist in sampling planning. This study aimed evaluate potential identifying specific management zones and its relationship with attribu...

BACKGROUND A key component of evaluating myocardial tissue function is the assessment of myofiber organization and structure. Studies suggest that striated muscle fibers are magnetically anisotropic, which, if measurable in the heart, may provide a tool to assess myocardial microstructure and function. METHODS To determine whether this weak anisotropy is observable and spatially quantifiable ...

Three different samples of soft magnetic material Proto-pasta, a composite iron and polylactic acid (PLA), were printed in the presence field then measured using vibrating sample magnetometer (VSM) to inspect effects printing has on samples’ properties. Multiple hysteresis measurements taken with respect angle for each various fields observe changes loss susceptibility. The Fe/PLA composites Ma...

A new germanide ThIrGe has been synthesized and characterized by X-ray diffraction, transmission electron microscopy, electrical resistivity, magnetic susceptibility thermodynamic measurements.
