Using scanning tunneling microscopy, we observe the alloying of Cr with an Fe(001) substrate for various coverages at two temperatures. At low Cr coverage, the alloy consists of individual Cr impurities surrounded by Fe. Elemental identification is possible using surface states observed via tunneling spectroscopy. The alloy may be the cause of several magnetic anomalies observed in Cr/Fe struct...

Interdiffusion coefficients of the refractory elements in Fe-Cr-X (X 1⁄4 Mo, W) and Fe-Mo-W ternary alloys were measured on the basis of the modified Boltzmann-Matano method for ternary systems. The cross interdiffusion coefficient, ~ D CrW was positive in Fe-Cr-W ternary alloy, indicating that W accelerates interdiffusion between Fe and Cr atoms. On the other hand, the cross interdiffusion coe...

Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...

background: the presence of heavy metals in the environment could constitute a hazard to food security and public health. these can be accumulated in aquatic animals such as fish. canned fish is consumed regularly in many countries. in this study, the levels of heavy metals cu, ni, fe and cr were evaluated in commercial canned fish products that are commonly consumed in iran. the canned fish st...

THE PRESENCE of small amounts of iron in chromium metal results in a lowering of the Neel temperature along with other anomalous diagram[l, changes in the phase r 1 , 2]. Suscepti­[I] N eel bility measurements 1 below the tem­perature show that the iron sites have associ­ated with them localized magnetic moments of about 1·4f.LIJ I· per iron atom and that the iron moments remain paramagnetic do...
