Microstructured Resonators for Electron Spin Resonance
... Sensitivity has many facets that lead to different, partly conflicting goals. In some cases, the main consideration is to obtain good signals from very dilute samples (concentration sensitivity). In other cases, one may need to detect the smallest possible number of spins. Here, we concentrate on mas ...

Magnetic Resonance Imaging of Surgical Implants Made from Weak
... Nevertheless, some materials with low magnetic susceptibility can also cause an artifact in MR images. It may be caused by large and rapidly switched magnetic field gradients which induce eddy currents in electrically conductive sample inserted into the MR scanner. These eddy currents produce additi ...

Magnetic Field Strength H
... The samarium-cobalt combinations have been around longer, and the SmCo5 magnets are produced for applications where their strength and small size offset the disadvantage of their high cost. The more recent neodynium materials like Nd2Fe14B produce comparable performance, and the raw alloy materials ...
