Spin-Flop Ordering from Frustrated Ferro- and Antiferromagnetic Interactions: A Combined Theoretical and Experimental Study of a Monolayer
C. Grazioli, Dario Alfè, S. R. Krishnakumar +8
The occurrence of a noncollinear magnetic structure at a Mn monolayer grown epitaxially on Fe(100) is predicted theoretically, using spinor density-functional theory, and observed…
Absence of local magnetic moments in Ru and Rh impurities and clusters on Ag(100) and Pt(997)
J. Honolka, K. Kuhnke, L. Vitali +8
The magnetism of quench-condensed Ru and Rh impurities and metal films on Ag(100) and Pt(997) has been studied using x-ray magnetic circular dichroism. In the coverage range betwee…
A microspectroscopic study of the electronic homogeneity of ordered and disordered Sr2FeMoO6
Dinesh Topwal, U. Manju, Sugata Ray +6
Besides a drastic reduction in saturation magnetization of disordered Sr2FeMoO6 compared to highly ordered samples, magnetizations as a function of the temperature for different di…
Direct observation of electronic domains in manganites by spatially resolved spectroscopy
D. D. Sarma, Dinesh Topwal, U. Manju +8
We use a spatially resolved, direct spectroscopic probe for electronic structure with an additional sensitivity to chemical compositions to investigate high-quality single crystal…
X-ray photoemission study of NiS_{2-x}Se_x (x = 0.0 - 1.2)
S. R. Krishnakumar, D. D. Sarma
Electronic structure of NiS_{2-x}Se_x system has been investigated for various compositions (x) using x-ray photoemission spectroscopy. An analysis of the core level as well as the…
Metal-insulator Crossover Behavior at the Surface of NiS_2
D. D. Sarma, S. R. Krishnakumar, E. Weschke +8
We have performed a detailed high-resolution electron spectroscopic investigation of NiS and related Se-substituted compounds NiSSe, which are known to be gapped in…
