Magneto-Optic Kerr Effect
... Lasers are typically used for MOKE experiments. When lasers are used with PEMs an effect called “modulated interference” may be present.4 Since the MOKE AC signals are typically very weak, great care must be taken to eliminate or reduce these effects. Useful techniques include: 1) use of anti-reflec ...

X-ray fluorescence
X-ray fluorescence (XRF) is the emission of characteristic ""secondary"" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
