“…This category represents the major research performed using ASPIC after the year 2000 (Potzger et al 2002, Prandolini et al 2004, Manzhur et al 2005a, Potzger et al 2005, Manzhur et al 2007. The basic idea behind these experiments is the fact that a surface offers a variety of different local structures, (terraces, steps, kinks, etc).…”

We review the research carried out using the apparatus for surface physics and interfaces (ASPIC), at ISOLDE, CERN. We give an overview of the research highlights since 2000, focusing on magnetic and non-magnetic metallic surfaces, and introduce the scientific program that will follow the upgrade which is currently underway, focusing on two-dimensional materials. ASPIC was formerly used for the growth of ultrathin metallic films and their characterization by means of perturbed angular correlation spectroscopy. Past research has mainly focused on the determination of the magnetic hyperfine field at the probe atom located on different sites at the surface such as terraces, kinks, steps as well as on the investigation of the static magnetic polarization at the interface between ferromagnetic and paramagnetic layers. Future research on two-dimensional materials using ASPIC is foreseen to focus on the investigation of structural and electronic properties of adatoms (adsorption sites, hybridization effects, intra-atomic charge transfer, magnetic moments, etc). We emphasize, in this context, the exceptional capabilities of ASPIC in terms of broad applicability, high precision and low detection limits.

“…To the best of our knowledge, few studies have investigated the magnetic properties of Ni ultrathin films on Pd(001), except for a study using perturbed angular correlation spectroscopy. 12) This is in contrast to the many studies on its film morphology and atomic structure. 11,[13][14][15] In this study, we investigated Ni-coverage dependence of the magnetic anisotropy and local magnetic moments of Ni atoms in Ni/Pd(001) using in situ sample fabrication and X-ray magnetic circular dichroism (XMCD).…”

“…This indicates a layer-by-layer growth (Frank-van der Merwe mode 20) ) up to 6 ML, which is consistent with previous studies. 12,13) To investigate the magnetic anisotropy of Ni/Pd(001), we measured M-H curves derived from the external-field dependence of the XMCD intensity at the Ni L 3 absorption edge. Photon incident angles were set to 0°(normal incidence) and 60°(grazing incidence) to detect the out-ofplane and in-plane magnetization, respectively.…”

“…Manzhur et al discussed magnetic anisotropy caused by lattice strain in Ni films and concluded that the thickness of d + reduces with the Ni lattice expansion. 12) In Ni/Cu(001), where a lattice expansion of 2.5% is estimated, the critical coverage is reported as d + = 7 ML. 9) In Ni/Cu 3 Au(001), whose lattice expansion is 6.1% at the interface, the value of expansion ratio is reduced to 4% above 5 ML, which leads to d + = 5.5 ML.…”

Coverage-dependent magnetic properties of Ni ultrathin films on Pd(001) was investigated using X-ray magnetic circular dichroism (XMCD). Magnetization curves and Ni L2,3 XMCD spectra were measured as a function of Ni coverage. These results revealed a spin reorientation transition from in-plane to out-of-plane as the Ni coverage increased. Ni 3d spin and orbital magnetic moments were evaluated using the magneto-optical sum rules. The presence of a magnetic dead layer inside the Ni film explains the Ni coverage dependence of spin magnetic moment.

Nanosheets of nickel with thickness equal to 0.6 nm have been grown within the interlayer spaces of Na-4 mica. The sheets are made up of percolative clusters of nanodisks. Magnetization characteristics indicate a superparamagnetic behavior with a blocking temperature of 428 K.The magnetic anisotropy constant as extracted from the coercivity data has been found to be higher than that of bulk nickel by two orders of magnitude. This is ascribed to a large aspect ratio of the nickel nanophase. The Bloch exponent is also found to be considerably different from that of bulk nickel because of a size effect. The Bloch Equation is still found to be valid for the two dimensional structures.
