TLDR
In this article, the authors used circularly polarized soft x-rays with an imaging photoelectron microscope to record images of magnetic domains at a spatial resolution of 1 micrometer.Abstract:
Circularly polarized soft x-rays have been used with an imaging photoelectron microscope to record images of magnetic domains at a spatial resolution of 1 micrometer. The magnetic contrast, which can be remarkably large, arises from the fact that the x-ray absorption cross section at inner-shell absorption edges of aligned magnetic atoms depends on the relative orientation of the photon spin and the local magnetization direction. The technique is element-specific, and, because of the long mean free paths of the x-rays and secondary electrons, it can record images of buried magnetic layers.read more

Recycling lower continental crust in the North China craton
Shan Gao,Shan Gao,Roberta L. Rudnick,Hong-Ling Yuan,Xiaoming Liu,Yongsheng Liu,Wen-Liang Xu,Wenli Ling,John C. Ayers,Xuan-Che Wang,Qing-Hai Wang +10 more
TL;DR: It is suggested that lower crustal foundering occurred within the North China craton during the Late Jurassic, and thus provides constraints on the timing of lithosphere removal beneath the NorthChina craton.

Lensless imaging of magnetic nanostructures by X-ray spectro-holography
Stefan Eisebitt,Jan Lüning,William F. Schlotter,M. Lörgen,Olav Hellwig,Wolfgang Eberhardt,Joachim Stöhr +6 more
TL;DR: This work demonstrates a versatile technique for imaging nanostructures, based on the use of resonantly tuned soft X-rays for scattering contrast and the direct Fourier inversion of a holographically formed interference pattern, which is a form of Fourier transform holography and appears scalable to diffraction-limited resolution.

Absorption of circularly polarized x rays in iron.
TL;DR: In the extended absorption region up to 200 eV above the Fermi level a small spin-dependent absorption is observed and thus is expected to give information on the magnetic neighborhood of the absorbing atom.

TL;DR: In this paper, the authors used the ac detection method which senses the force gradient acting on a small magnetic tip due to fields emanating from the domain structure in the sample, and showed that the final 20 μm is essentially single domain with magnetization approximately parallel with the tip axis.
