Title: Ground-state wave function of plutonium in PuSb as determined via x-ray magnetic circular dichroism

Abstract

Measurements of x-ray magnetic circular dichroism (XMCD) and x-ray absorption near-edge structure (XANES) spectroscopy at the Pu M-4,M-5 edges of the ferromagnet PuSb are reported. Using bulk magnetization measurements and a sum rule analysis of the XMCD spectra, we determine the individual orbital [mu(L) = 2.8(1)mu(B)/Pu] and spin moments [mu(S) = -2.0(1)mu(B)/Pu] of the Pu 5f electrons. Atomic multiplet calculations of the XMCD and XANES spectra reproduce well the experimental data and are consistent with the experimental value of the spin moment. These measurements of < L-z > and < S-z > are in excellent agreement with the values that have been extracted from neutron magnetic form factor measurements, and confirm the local character of the 5f electrons in PuSb. Finally, we demonstrate that a split M-5 as well as a narrow M-4 XMCD signal may serve as a signature of 5f electron localization in actinide compounds.

Electronic structure and x-ray magnetic circular dichroism in Cu{sub 3}Au-type transition metal platinum alloys

Journal Article Antonov, V N ; Harmon, B N ; Yaresko, A N - Physical Review B

The electronic structure and x-ray magnetic circular dichroism (XMCD) in XPt{sub 3}(X= V, Cr, Mn, Fe, Co, Ni) and X{sub 3}Pt(X= Fe, Co, Ni) compounds are investigated theoretically from first principles, using the fully relativistic Dirac LMTO band structure method. The electronic structure is obtained with the local spin-density approximation (LSDA). Theoretically calculated spin and orbital magnetic moments are found to be in good agreement with neutron and XMCD experimental data. An interpretation for systematic trends seen in the orbital and spin magnetic moments of the series XPt{sub 3} is presented by analyzing the calculated spin- and orbital-projected density ofmore »« less

The solid solutions between ilmenite (FeTiO{sub 3}) and hematite (α-Fe{sub 2}O{sub 3}) have recently attracted considerable attention as a spintronic material due to their interesting magnetic and electrical properties. In this study, the electronic and magnetic structures of epitaxially grown 0.6FeTiO{sub 3}·0.4Fe{sub 2}O{sub 3} solid solution thin films were investigated by combining x-ray absorption near-edge structure (XANES), x-ray magnetic circular dichroism (XMCD) for two different crystallographic projections, and first-principles theoretical calculations. The Fe L-edge XANES and XMCD spectra reveal that Fe is in the mixed-valent Fe{sup 2+}–Fe{sup 3+} states while Fe{sup 2+} ions are mainly responsible for the magnetization. Moreover,more »« less

X-ray magnetic circular dichroism at the U M{sub 4,5} absorption edges of UFe{sub 2}

Journal Article Finazzi, M ; Sainctavit, P ; Laboratorie de Mineralogie et Cristallographie de Paris, CNRS URA9, Universites de Paris 6 et 7, 75252 Paris ; ... - Physical Review, B: Condensed Matter

We present an x-ray magnetic circular dichroism study performed at the U M{sub 4,5} edges on UFe{sub 2}, a ferromagnet with almost itinerant 5f electrons. The analysis of the branching ratio of the U M{sub 4,5} edges confirms the fact that the occupation number of the 5f states in UFe{sub 2} is lower than in other compounds where the f electrons are more localized. Magnetic circular dichroism effects are observed consistently with the presence of an orbital 5f magnetic moment which aligns parallel to the total magnetic moment. In agreement with a polarized neutron study, we find a nearly perfectmore »« less

L-edge X-ray absorption and X-ray magnetic circular dichroism of oxygen-bridged dinuclear iron complexes

Journal Article Peng, G ; Elp, J van ; Jang, H ; ... - Journal of the American Chemical Society; (United States)

Iron L-edge X-ray absorption and X-ray magnetic circular dichroism (XMCD) spectroscopy have been used to study the electronic structure of dinuclear iron-oxo complexes with different types of magnetic and electronic interactions between the iron sites. Trapped-valence systems exhibit L-edges with clear multiplet structure. The L-edges of trapped-valence Fe[sup II]Fe[sup III] complexes such as [Fe[sup III,II]2(salmp)[sub 2]][sup [minus]] and [Fe[sub 2][sup III,II](bpmp)([mu]-O[sub 2]CC[sub 2]H[sub 5])[sub 2]][sup 2[center dot]] can be interpreted as the sum of distinct Fe(II) and Fe(III) component spectra. Furthermore, an atomic multiplet theory including adjustable ligand field splittings can successfully simulate the Fe(II) and Fe(III) X-ray absorption. Reasonablemore »« less

Measurement and multiple-scattering calculation of Cu K-edge x-ray magnetic circular dichroism spectra from an exchange-coupled Co/Cu multilayer

Journal Article Nagamatsu, S ; Matsumoto, H ; Fujikawa, T ; ... - Physical Review. B, Condensed Matter and Materials Physics

Small but significant x-ray magnetic circular dichroic (XMCD) absorptions are observed from an exchange-coupled Co/Cu multilayer at the Cu K edge. Multiple-scattering calculations including the spin-orbit interaction show that the Cu dichroism is almost entirely due to the spin-dependent scattering of photoelectrons by the exchange potentials of Co atoms at the interface. Possible small magnetic moments induced on Cu account for a marginal fraction of the observed Cu dichroism. The calculated XMCD spectra are highly sensitive to the local magnetic structure around the x-ray absorbing site. Layer-resolved magnetic absorption spectra calculated near the K edge of Cu demonstrate that themore »« less
