Many questions remain concerning the viability and productivity of seeding native legumes in the Canadian Prairies for forage production. Field research was conducted with four native legume species (Astragalus flexuosus, Dalea purpurea, Hedysarum bo

Heat capacity measurements of protonated lithium acetate dihydrate show a structural phase transition at T = 12 K. This finding is in contrast to earlier work, where it was thought that only the deuterated compound undergoes a low temperature structu

Three-axes elastic neutron scattering measurements demonstrate that the five-fold modulated phase (phase 1/5) of BCCD exhibits under electric field a phase transition without change of superlattice periodicity. Through the monitoring of high-order sa

As an alternative to the usual Landau-Ginzburg-type continuous field approximation, a free energy featuring two anticrossed phonon branches and defined in a discrete lattice is proposed for dealing with modulated phases with inherent discrete lattice

This paper reports on the first structural results of a (P, T) phase diagram study of the antiferroelectric (Tc=353 K) TlD2PO4 by means of neutron powder diffraction. The temperature range studied was from room temperature to 400 K, and up to 8 kbar

We present the results of mean-field calculations on a symmetry based semimicroscopic model for betaine calcium chloride dihydrate. The model takes into account the three degrees of freedom associated with the lowest energy phonon branches as relevan

The crystal structure of the antiferroelectric phase of TlD2PO4, deuterated thallium dihydrogenphosphate, has been determined from single-crystal neutron diffraction data collected at room temperature. The para-antiferroelectric transition (T_c^d = 3

A theorem is proven demonstrating the existence of phonon symmetry selection rules, independent of particular structural features, for coherent inelastic neutron scattering by crystals. The resulting systematic absences depend only on the mode symmet

The mechanism of the para-antiferroelectric phase transition at 353 K in has been investigated by coherent elastic and inelastic neutron scattering. The structural phase transition is shown to arise from the condensation of a diffusive mode to which
