We report the first observation of a nonreciprocal x-ray linear dichroism caused by the time-reversal odd, real part zeta of the complex gyrotropy tensor zeta(*) which is dominated by electric dipole-electric quadrupole E1E2 interference terms. A non

X-ray magnetic circular dichroism spectra have previously been obtained by switching the polarization helicity with a diamond quarter-wave plate (QWP) and keeping the applied magnetic field on the sample as an independent variable [Giles, Malgrange,

The differential absorption and the differential change in the polarization state of an X-ray beam propagating inside a gyrotropic crystal are described using a 4 X 4 Muller matrix, the 16 elements of which are related to the anisotropic components o

In a large Czochralski-grown Si1−x Ge x (0.02 \leq x \leq 0.07) gradient crystal, diffraction patterns have been measured in symmetrical Laue geometry using synchrotron radiation in the energy range 100–200 keV. The experimental data are in very

The case of a crystal containing a thin buried layer is analysed within the dynamical theory of X-ray diffraction. In this case, the upper thin part of the crystal, above the buried layer, is only shifted with respect to the lower bulk part. The main

A quarter wave plate made of a 16 μm thin silicon single crystal was inserted in front of a double crystal monochromator which was used as linear polarimeter for Bragg angles close to 45°. This allowed us to demonstrate that, at 2.836 keV, the circ

A quarter-wave plate made of a ca 16 mum-thick silicon single-crystal was used at energies as low as 2.8 keV to convert circularly polarized photons into linearly polarized photons. Coupled to a linear polarimeter, this quarter-wave plate enabled the

X-ray Bragg-case diffraction in crystals distorted by a constant strain gradient is studied theoretically. The rocking curves and intensity distributions of the standing-wave fields are calculated for several data sets corresponding to real physical

Circular magnetic x‐ray dichroism experiments require circularly polarized x rays usually provided by bending magnet synchrotron radiation below or above the orbit plane. It is shown here that a very promising alternative consists of using linearly
