Electron paramagnetic resonance study of thermally treated bismuth subgallate

This result is shown in Figure 3.The [La.sub.0.7][Ca.sub.0.24][Sr.sub.0.06]Mn[O.sub.3] single crystal undergoes a phase transition from paramagnetic to a ferromagnetic state at the Curie temperature [T.sub.c]= 277 K.

These include increasing the echo time, which allows greater time for the dephasing of the paramagnetic signal; thinner scanning sections, which increase the signal-to-noise ratio; increasing the magnetic field strength; and image postprocessing techniques such as susceptibility-weighted imaging, which "incorporates the phase shift as well as the magnitude effects of the iron deposits to increase their visibility."

Compared with conventional [T.sub.2]-weighted MRI, [T.sub.2.sup.*]-weighted MRI does not use a refocusing pulse, "so the dephasing caused by the paramagnetic iron is accentuated by the [T.sub.2.sup.*]-weighted technique," Dr.
