Demagnetization curves for nanocrystalline Nd 2 Fe 14 B magnets were calculated by using the micromagnetic finiteelement technique. The shape of the grains is either cubic or tetrakaidecahedral. If the grain number N of the magnet is small, the calculated curve, especially that for m 0i H c , strong
## Abstract The ability to measure proton exchange rates in tissue using MRI would be very useful for quantitative assessment of magnetization transfer properties, both in conventional MT imaging and in the more recent chemical exchange saturation transfer (CEST) approach. CEST is a new MR contrast
