In: VACUUM. - : PERGAMON-ELSEVIER SCIENCE LTD. - 0042-207X. ; 46:8-10, s. 1211-1214
-
Journal article (other academic/artistic)abstract
- We report magnetic circular X-ray dichroism (MCXD) measurements of ultrathin Ni films grown on Cu(?OO). The Curie temperature of the films is determined by means of a.c. MXCD susceptibility, a technique that allows T-c to be probed precisely and unambiguo

PAIR POTENTIALS IN THE SEXAFS ANALYSIS
- 1995
-
In: PHYSICA B. - : ELSEVIER SCIENCE BV. - 0921-4526. ; 209:1-4, s. 431-435
-
Journal article (other academic/artistic)abstract
- An overview for a dynamical SEXAFS analysis for several systems is presented in terms of effective pair potentials. Model potentials of Madelung type are found to describe well the adsorption of N, O, O-2 on Cu and Ni metal surfaces. The potential paramet

ENHANCEMENT OF ORBITAL MAGNETISM AT SURFACES - CO ON CU(100)
- 1995
-
In: PHYSICAL REVIEW LETTERS. - : AMER INST PHYSICS. - 0031-9007. ; 75:8, s. 1602-1605
-
Journal article (other academic/artistic)abstract
- By combining magnetic circular x-ray dichroism experiments with first principles electronic structure calculations, we demonstrate that the orbital contribution to magnetism can be strongly enhanced at surfaces. This effect is illustrated for Co grown on

-
Journal article (other academic/artistic)abstract
- The presence of oscillatory structures in the atomic x-ray absorption background is reported for the first time for surface EXAFS of c(2x2)NiCu(100) and (2x3)N/Cu(110). The experimental data for N/Cu(110) are compared to FEFF7 calculations of the oscillat
