Slit-collimated Laue diffraction using synchrotron radiation: an examination of the paraelectric-to-ferroelectric phase transformation in ammonium sulfate

The use of the synchrotron Laue diffraction technique with a slit-collimated incident beam as a structural probe to examine solid-state phase transformations in single crystals is presented. The utility of the method is demonstrated through a study of the paraelectric-to-ferroelectric phase transition in ammonium sulfate at 223 K.
