Magnetic memory in discrete media observed by coherent soft x-ray resonant scattering
نویسندگان
چکیده
Using soft x-ray resonant magnetic scattering with a coherent beam, we find evidence for memory effects in the magnetic configuration of a periodic array of submicron ferromagnetic lines under external magnetic field. The memory effect is explained by the dipolar coupling between the lines which is lost when the sample is saturated by the external magnetic field. 9 Author to whom any correspondence should be addressed.

Magnetic domain fluctuations in an antiferromagnetic film observed with coherent resonant soft x-ray scattering.
We report the direct observation of slow fluctuations of helical antiferromagnetic domains in an ultrathin holmium film using coherent resonant magnetic x-ray scattering. We observe a gradual increase of the fluctuations in the speckle pattern with increasing temperature, while at the same time a static contribution to the speckle pattern remains. This finding indicates that domain-wall fluctua...
متن کاملPolarization effects in coherent scattering from magnetic specimen: Implications for x-ray holography, lensless imaging, and correlation spectroscopy
We present resonant coherent small-angle scattering from sub-mm magnetic domains in an in-line holography geometry. By varying the polarization of the incident soft x rays the interference between the reference wave propagating from a pinhole and scattered object wave can be switched ‘‘on’’ or ‘‘off.’’ The referenceobject interference contribution in the scattering can be isolated by combining ...
متن کاملDispersion of magnetic excitations in the cuprate La2CuO4 and CaCuO2 compounds measured using resonant x-ray scattering.
By resonant inelastic x-ray scattering in the soft x-ray regime we probe the dynamical multiple-spin correlations in the antiferromagnetic cuprates La2CuO4 and CaCuO2. High resolution measurements at the copper L3 edge allow the clear observation of dispersing bimagnon excitations. Theory based on the ultrashort core-hole lifetime expansion fits the data on these coherent spin excitations witho...
متن کاملAcquiring molecular interference functions of X-ray coherent scattering for breast tissues by combination of simulation and experimental methods
Background: Recently, it has been indicated that X-ray coherent scatter from biological tissues can be used to access signature of tissue. Some scientists are interested in studying this effect to get early detection of breast cancer. Since experimental methods for optimization are time consuming and expensive, some scientists suggest using simulation. Monte Carlo (MC) codes are the best...
متن کاملSoft x-ray magnetic scattering evidence for biquadratic coupling in CoÕCu multilayers
Soft x-ray resonant magnetic scattering has been used to study the magnetic structure of sputtered Co/Cu multilayers. A pure magnetic peak, at half the scattering vector of the structural Bragg peak from the multilayer, was observed from layers with and without deliberate oxygen contamination in the middle of the copper spacer layer. With increasing field in the sample plane, the magnetic peak ...
