We present an x-ray spectromicroscopic investigation of single-crystalline magnetic FeMn/Co bilayers on Cu 001 , using x-ray magnetic circular dichroism and x-ray magnetic linear dichroism XMLD at the Co and Fe L3 absorption edges in combination with photoelectron emission microscopy. Using the magnetic coupling between the ferromagnetic Co layer and the antiferromagnetic FeMn layer, we are abl...

The effects of YBa2Cu3O72d ~YBCO! cap layers on the magnetic and electronic properties of La0.7Sr0.3MnO3 ~LSMO! underlayers was determined by x-ray magnetic circular dichroism and x-ray absorption spectroscopy techniques. The YBCO caps alter the LSMO in a way that effectively decreases the concentration of La at the LSMO/YBCO interface. © 2000 American Institute of Physics. @S0021-8979~00!62908-0#

Detailed X-ray magnetic circular dichroism measurements as a function of temperature are reported in ErCo2 at the Co L2,3 edges. The application of magneto-optical sum rules allows for the determination of the Co orbital and spin magnetic moments both in the ferrimagnetic and paramagnetic phases. In agreement with the predictions of Hund’s third rule, Co orbital and spin moments are parallel th...

Ferromagnetic resonance (FMR) spectroscopy, x-ray magnetic circular dichroism (XMCD) spectroscopy and magnetic transmission soft x-ray microscopy (MTXM) experiments have been performed to gain insight into the magnetic anisotropy and domain structure of ultrathin Co9Ni multilayer films with a thin permalloy layer underneath. MTXM images with a spatial resolution better than 25 nm were obtained ...

We describe how first principle calculations can play a key role in the interpretation of X-ray absorption near-edge structure (XANES) and X-ray magnetic circular dichroism (XMCD) spectra for a better understanding of emergent phenomena in condensed matter physics at high applied pressure. Eu compounds are used as case study to illustrate the advantages of this methodology, ranging from studies...

The spin dynamics of ferromagnetic thin films following an excitation by ultrashort 100-fs near-infrared laser pulses has recently received much attention. Here, a new approach is described using x-ray magnetic circular dichroism to investigate demagnetization and magnetization switching processes. In contrast to magneto-optical measurements, x-ray dichroism has the advantage of determining sep...

We report the observation of a magnetic moment on vanadium embedded in copper. Using x-ray-absorption spectroscopy and x-ray magnetic circular dichroism we show that the vanadium atomic magnetic moment is strongly dependent on the formation temperature of the VCu alloy. The absorption spectra allow us to distinguish the electronic transitions which are the signature of the magnetic state from t...

background: recently, botulinum neurotoxin (bont)-derived recombinant proteins have been suggested as potential botulism vaccines. here, with concentrating on bont type e (bont/e), we studied two of these binding domain-based recombinant proteins: a multivalent chimer protein, which is composed of bont serotypes a, b and e binding subdomains, and a monovalent recombinant protein, which contains...
