October 2018. It starts with an introduction to the physics of modern X-ray sources followed by a general overview of magnetism. Next, light / matter interaction in the X-ray range is covered with emphasis on different types of angular dependence of X-ray absorption spectroscopy and scattering. In the end, two domains where synchrotron radiation-based techniques led to new insights in condensed matter physics, namely spintronics and superconductivity, are discussed. The book is intended for advanced students and researchers to get acquaintance with the basic knowledge of X-ray light sources and to step into synchrotron-based techniques for magnetic studies in condensed matter physics or chemistry. 410 0$aSpringer Proceedings in Physics 606 $aSpectrum analysis, spectrochemistry, mass spectrometry$2bicssc 606 $aAtomic & molecular physics$2bicssc 606 $aOptical physics$2bicssc 606 $aFluid mechanics$2bicssc 606 $aCircuits & components$2bicssc 610 $aSpectroscopy and Microscopy 610 $aAtomic, Molecular, Optical and Plasma Physics 610 $aOptics, Lasers, Photonics, Optical Devices 610 $aCondensed Matter Physics 610 $aMagnetism, Magnetic Materials 610 $aSemiconductors 610 $aX-Ray Spectroscopy 610 $aSynchrotron Techniques 610 $aLaser-Matter Interaction 610 $aStrongly Correlated Systems 610 $aMagnetism 610 $ax-ray light sources 610 $ax-ray scattering 610 $aspintronics 610 $aOpen Access 610 $aGauge invariance in spectroscopy 610 $amolecular magnestism 610 $amagnetic semiconductors 610 $aSpectrum analysis, spectrochemistry, mass spectrometry 610 $aScientific equipment, experiments & techniques 610 $aAtomic & molecular physics 610 $aOptical physics 610 $aApplied optics 610 $aMaterials / States of matter 610 $aElectricity, electromagnetism & magnetism 610 $aElectronic devices & materials 615 7$aSpectrum analysis, spectrochemistry, mass spectrometry 615 7$aAtomic & molecular physics 615 7$aOptical physics 615 7$aFluid mechanics 615 7$aCircuits & components 700 $aBulou$b Herve?$0852014 701 $aJoly$b Loi?c$0852015 701 $aMariot$b Jean-Michel$0852016 701 $aScheurer$b Fabrice$0852017 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910473457003321 996 $aMagnetism and Accelerator-Based Light Sources$91902408 997 $aUNINA
