Static conversion of Bloch-line number and the self-collapse of hard bubbles

Abstract

In bubbles carrying at least 100 Bloch lines, called superhard bubbles, the phenomenon of static conversion of the Bloch wall has been observed. Two experiments will be described in detail: (i) the dependence of the number of Bloch lines as a function of the temperature at which the material has been treated and (ii) the phenomenon of the self-collapse of bubbles having Bloch lines in a supercompressed state.

“…The reasons for such a behaviour of domain walls have not been clarified so far. It seems, that this behaviour described above of domain walls can be caused by phenomenon similar to the static conversion [14].…”
