Phys. Rev. Lett. 90, 077404 (2003) [4 pages]Field-Induced Magnetic Circular X-Ray Dichroism in Paramagnetic Solids: A New Magneto-Optical EffectReceived 8 July 2002; published 21 February 2003 It is demonstrated that for paramagnetic solids an external magnetic field—in analogy to the magneto-optical Kerr effect in the visible regime of light—gives rise to a magnetic circular dichroism in x-ray absorption (MCXD). A detailed description of this new field-induced magneto-optical phenomenon is given. In particular it is shown that the resulting dichroic spectra may be used to deduce the spin and orbital susceptibility in a component resolved way by making use of a modified form of the MCXD sum rules. © 2003 The American Physical Society URL:
