The alloys were exposed to a static magnetic field and then tested in creep under uniaxial tension. The morphology of the alloys was studied by scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. Their specific heat and the work done in plastic deformation were calculated using thermomechanical data. The results demonstrate that there is a relation between magnetostriction, mechanical stress on the matrix–inclusion interface, and energy dissipation during deformation. Magnetic pretreatment of the material has been shown to increase its specific heat by five times (from 0.05 to 0.26 J/m3) and the work done in its deformation by 44% (from 0.72 to 1.04 J/m3). The observed increase in Taylor coefficient (from 0.07 to 0.25) and latent energy (from 0.67 to 0.78 J/m3) is due to the stress redistribution on the matrix–inclusion interface as a consequence of magnetostriction. The estimated magnetostriction-induced mechanical stress exceeds the creep limit of the matrix, which accounts for the increase in energy dissipation. The results of this study can be useful in designing “smart” materials with programmable properties that can be controlled by varying the composition, particle size, and percentage of a magnetically active filler in a nonmagnetic matrix.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"62 2","pages":"199 - 206"},"PeriodicalIF":0.5,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we report characteristics of an X-ray monochromator designed for operation in a wide energy range. The working principle of the instrument relies on X-ray diffraction. The diffracting element is a pyrolytic graphite crystal. Rotating it through a preset angle allows monochromatic radiation to be isolated from the bremsstrahlung of the X-ray tube. We demonstrate that, with this instrument, one can obtain a monochromatic X-ray beam in the energy range 15–100 keV with monochromaticity at a level from 1.5 to 9% (which meets requirements for detector energy calibration accuracy). In addition, we show that controlled monochromatic radiation can be generated using readily available laboratory components.

The ability to determine the exact chemical composition of synthesized YIG is a critical issue for not only the matrix elements (Fe and Y), but also impurity components (Li, Be, B, Na, Mg, Al, Si, P, K, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Zr, Nb, Mo, Cd, Sn, Sb, Te, Ba, La, Ce, Sm, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Tl, Pb, Bi, Th, and U), because the presence of impurities at a level above 10–2 wt % causes a considerable broadening of its ferromagnetic resonance (FMR) line and impairs properties of thin-film structures.

We describe specific features of the preparation of thin-film structures containing Y3Fe5O12 film on a gallium arsenide substrate by a new, nonepitaxial method proposed by us and demonstrate the effect of the impurity composition of YIG on the structure and properties of such films. To prevent interfacial interaction between Y3Fe5O12 and GaAs during film crystallization, an AlOx barrier layer was first grown on the substrate by sputter deposition.

GFEs were prepared ex situ by electrodeposition of a gold layer onto the surface of a rotating glassy carbon electrode by potentiostatic electrolysis for 300 s from a 1 mM HAuCl4 solution at –300 mV. Under the optimized electroaccumulation parameters, the stripping current for arsenic was linear from 10 to 200 μg/L, and the limit of detection was 1 μg/L with an accumulation time of 120 s.

The microwave-cured GFRPs have strength properties similar to those of the thermoset GFRPs, namely, an elastic modulus of up to 48.6 GPa and a flexural strength of up to 1072 MPa, but with slightly lower microhardness up to 0.97 GPa, which is related to the peculiarities of structure formation during volumetric heating.
