A TEM study of the incommensurate modulated structure in Sr2CuO3+ ~ superconductor synthesized under higla pressure A. Evolution of the incommensurate modulated structure and the electronic structure with post-heat treatment
Transmission electron imaging, diffraction and spectroscopy techniques are utilized to study the changes in modulated structure and aspects of electronic structure of the high oxygen pressure synthesized superconductor: Sr2CuO3+ 8. The presence of an incommensurate modulated superstructure in Sr2CuO3+ n and its dependence on post-annealing treatment is documented. Transmission EELS indicates th...
متن کاملThe incommensurate structure of K3InPO42.
The incommensurately modulated structure of K(3)In(PO(4))(2) has been solved and refined. The origin of the modulation relates to the ordering of K cations within the hexagonal close packing of the PO(4) anions. The driving forces for the modulation of the other cations are In-P and K-P interactions. The modulation of O atoms of rigid PO(4) units follows the cations in order to stabilize the In...
متن کاملContinuous transformations of cubic minimal surfaces
Although the primitive (P ), diamond (D) and gyroid (G) minimal surfaces form the structural basis for a multitude of self-assembling phases, such as the bicontinuous cubics, relatively little is known regarding their geometrical transformations, beyond the existence of the Bonnet isometry. Here their highest symmetry deformation modes, the rhombohedral and tetragonal distortions, are fully elu...
متن کاملDirect observation of incommensurate structure in Mo3Si.
Z-contrast imaging, electron diffraction, atom-probe tomography (APT) and density functional theory calculations were used to study the crystal structure of the Mo3Si phase which was previously reported to have an A15 crystal structure. The results showed that Mo3Si has an incommensurate crystal structure with a non-cubic unit cell. The small off-stoichiometry in composition of the sample which...
متن کاملField-induced incommensurate spin structure of TbNiAl4
TbNiAl4 exhibits incommensurate and commensurate magnetic ordering as a function of temperature. As a function of applied field it undergoes a series of magnetic phase transitions. The first of these transitions, into an intermediate spin arrangement, is the source of a large inverse magnetocaloric effect, an unusual result given that an aligning field is being applied. This has potential uses ...
