and magnetic properties of the ThCr2Si2-type solid solution LaMn2(Ge1−xSix)2 (x = 0.0 to 1.0) have been investigated employing a combination of X-ray diffraction, magnetization and neutron diffraction measurements, which allowed establishing a magnetic composition-temperature phase diagram. ...
Generally, the x-ray fluorescence spectrum (secondary spectrum) of the sample is excited by the primary radiation of the x-ray tube. The limit of element detection by the secondary fluorescence spectrum is ∼10−3–10−4%. When the radiation is excited by protons with energies of 1–2...
