“…The coherence length of the quasicrystal-phase grain is calculated by measuring the full width at half maximum (FWHM) value of the (110 000) peak, and was estimated in the range of 140 A $ 200 A, which is shorter than the ones measured by Azhazha et al [22] and Zhang et al [23]. The quasi-lattice constants are decreased (from 5.28 to 5.16 A) as increasing the Ti concentration (from 33 to 55 at%), suggesting that Ti occupies the sites for Zr and reduces the cell sizes due to the smaller atomic size.…”

Abstract. Quasicrystals made with Ti, Zr and Ni are good candidate materials studying the magnetic properties of aperiodic structure because the role of Ni in stabilization of the quasicrystal phase is important. Various magnetic states in quasicrystals have been reported including diamagnetism, paramagnetism, spin glass, ferromagnetism and ferrimagnetism. We prepared Ti--Zr--Ni quasicrystals by rapid quenching method. The magnetization (M) of Ti 50 Zr 33 Ni 17 quasicrystal was measured as a function of applied magnetic field (H) and a temperature by using a vibrating sample magnetometer (VSM). When the magnetic fields of higher than 2000 G were applied, the magnetization values were decreased as increasing temperature. The field-cooling (FC) and zero-field-cooling (ZFC) magnetization of the samples were also measured and showed no significant difference in magnetization behavior. Our combined results demonstrated that the rapidly quenched Ti--Zr--Ni quasicrystals exhibit paramagnetic properties with no hint of a measurable magnetic hysteresis. It is shown that Ti 50 Zr 33 Ni 17 quasicrystals demonstrate paramagnetic characteristic to the maximum applied magnetic field of 10 000 Oe. Interestingly, magnetization fluctuation was noticed in the regions of high magnetic field and at low temperature (25-300 K).

“…In spectrums (B) and (C), all the diffraction peaks could be indexed to the Ti 2 Ni-type face centered cubic (fcc) phase (Fd3m), which was first proposed as the appropriate crystal approximant for some Ti-based i-phases, while the electron diffraction pattern (EDP) along fivefold direction for the Ti 1.8 V 0.2 Ni ribbons demonstrated the presence of the i-phase. This inconsistence of analysis might arise not only from too little amount of i-phase that could not be detected by XRD, but also from the dangers of using only conventional X-ray powder diffraction to characterize these alloy ribbons that have already been put forward [14]. Previous calculations have shown that powder patterns from high-order approximants which formed with local icosahedral symmetry closely resemble those from the true i-phase [15].…”

“…Fortunately, a series of thermodynamically stable quasicrystalline alloys of high structural quality in the icosahedral Al-Cu-(Fe,Ru,Os) [34], Al-Pd-(Mn,Re) [35], and Zn-Mg-RE systems [36], and the decagonal Al-Co-(Cu,Ni) system [37,38], were discovered during the period from 1987-1994. Titanium based stable icosahedral QCs in the Ti-Zr-Ni alloy system were also reported in 1994 [39], and stable QCs belonging to the Zn-Sc-RE, Cd-Mg-RE, or (Au,Ag)-In-Ca systems have been announced during the last decade [40]. The first stable binary QC was discovered in 2000 in the Cd-Yb(Ca) system [41].…”

This Special Issue aims at gaining a deeper understanding on the relationship between the underlying structural order and the resulting physical properties in aperiodic systems, including quasicrystalline and related complex metallic alloys, photonic quasicrystals, and other structures exhibiting long-range aperiodic order. This Special Issue contains 12 papers which highlight recent developments in quasiperiodic crystal structure, photonic quasicrystals and related optical devices, the intrinsic electrical, thermal, and mechanical properties of icosahedral and decagonal metallic alloys, and the nature of chemical bonding in intermetallic compounds, from a multidisciplinary perspective. In light of the results presented in the contributions collected in this Special Issue, we can confidently expect that new insights into the interdisciplinary science of quasicrystals will be gained in the years to come, providing a sharper picture of their structures and related physical properties, and spurring further progress in practical issues related to both materials engineering science and nanotechnology.
