G Schaack - Ferroelectrics, 1990 - Taylor & Francis
Phase transitions in betaine compounds are reviewed. Some topics are selected for detailed presentation: Effects of reorientation and frustration in the (BA-DBA)-system and the (BA-BP) …
In this book some 50 papers published by KA Muller as author or co-author over several decades, amplified by more recent work mainly by TW Kool with collaborators, are …

BCCD exhibits a sequence of structural phase transitions from a high-symmetry orthorhombic phase to different commensurate or incommensurate phases modulated along …
Betaine calcium chloride dihydrate exhibits a sequence of over eleven structurally modulated phases, as well as a reentrant incommensurate phase. This work shows that a …
Betaine calcium chloride dihydrate exhibits a sequence of structural transitions from a Pnma phase to different commensurate or incommensurate phases modulated along the c axis. By …

An elastic-neutron-scattering study of partially deuterated dihydrate betaine calcium chloride (D-BCCD) is reported. We obtain direct diffraction evidence for the occurrence of a …
G Schaack, M Le Maire - Ferroelectrics, 1998 - Taylor & Francis
A review of the presently available experimental information on the modulated phases of BCCD, which display a devil's-staircase behavior, is given. Some basic experimental results …
We construct a symmetry-based, competing-interaction model for the phase-transition sequence in betaine calcium chloride dihydrate (BCCD). Our model qualitatively reproduces …
MR Chaves, JM Kiat, W Schwarz, J Schneck… - Physical Review B, 1993 - APS
In this work we present a study of elastic neutron scattering in deuterated betaine calcium chloride dihydrate under hydrostatic pressure. This study provides clear evidence for the …
