Figure 7
Neutron transmission images of the BaBrCl:0.1% Eu sample measured at the end of the heating/cooling cycles, when no apparent changes in the sample were observed. The arrows indicate whether the sample was cooled or heated between two consecutive images. The bottom part of the sample was never melted and remained in the original charge condition. Most of the contrast in these images is due to Eu attenuation of the cold neutrons of the BOA beamline facility. The dashed lines indicate the approximate position of the interface between the melted and original charge sections of the sample. |
