Crystal structure determination of a new monoclinic phase in NiMn system in a self-assembled chessboard-like microstructure

Journal of Applied Physics, 2023
Vacuum induction melted equi-atomic NiMn alloy has been studied through x-ray diffraction (XRD) and transmission electron microscopy (TEM). The XRD pattern of the as-solidified alloy may be matched with the tI2 η′-NiMn phase and the cF4 Ni3Mn phase simultaneously.

Noncritical acousto-optic Bragg phase matching: analysis of orthorhombic and monoclinic crystal systems

Applied Optics, 2021
Anisotropic acousto-optic diffraction in crystals is the fundamental phenomenon that is used to design acousto-optic tunable filters. Noncritical and quasicollinear phase-matching geometries of Bragg acousto-optic diffraction are compared for acoustic symmetry planes in four crystal systems (tetragonal, trigonal, orthorhombic, and monoclinic).

Re-examination of the Ca-Ga system and crystal structure of CaGa4, a monoclinic distortion of the BaAl4 type

Journal of the Less Common Metals, 1989
Abstract The gallium-rich region of the CaGa system (64.9 – 84.6 at.% Ga) was re-examined by X-ray methods. In addition to the CaGa 2 phase with the CaIn 2 structure type, another phase, CaGa 2 + x , was found in a limited homogeneity range, being 0.1 ⩽ x ⩽ 0.4, with crystal structure derived from the AlB 2 type.

On the constitutive relations for anisotropic materials—Triclinic, monoclinic, rhombic, tetragonal and hexagonal crystal systems

International Journal of Engineering Science, 1974
Abstract We consider constitutive relations of the form W = W( B ,…, C ) where W is a scalar polynomial function of the components of B,…,C which is invariant under the group A of transformations describing the symmetry of the material considered. We make no restrictions as to the number or kind of quantities B,…,C appearing as arguments of

Observations on dislocations in manganese(II) formate dihydrate, sucrose, and other crystals of the monoclinic system

Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1970
By etching the cleavage faces of manganese(II) formate dihydrate crystals with ethanol the nature of the dislocations present in this solid have been identified and shown to be almost identical with those that occur in sucrose, which has a similar space-group. The three major types of dislocation so far identified in monoclinic crystals are {h0/}[010],

The molecular dipole model in monoclinic systems: A study of the sulfate internal optic modes in Li2SO4⋅H2O crystals

The Journal of Chemical Physics, 1977
The sulfate ion internal optic modes in monoclinic lithium sulfate monohydrate (Li2SO4⋅H2O) are studied using a molecular dipole model. The polarization direction of the B symmetry phonons lies in the a–c plane, however a specific direction is not given by symmetry considerations.
