“…28 In the present work, we focus on the investigation of Fe/fcc-Mn bilayers with only in-plane magnetic anisotropy by choosing the thicker 8 ML Fe layer with the stronger in-plane shape anisotropy. According to previous works, 37,38 the anisotropy of Fe film was found to be biaxial aligning in in-plane 110 directions [with respect to the fcc-Cu 3 Au(001) crystalline axis]. The structure of the films was monitored by low energy electron diffraction (LEED) and LEED I/V.…”

We present a direct observation of a flipping magnetization of a uniform Fe film/wedged-Mn bilayer induced by a biquadratic-type exchange coupling established at the interface. The element-resolved magnetic imaging shows that the Fe film exhibited a flipping of magnetization between the [100] and [010] directions with a periodicity of one monolayer Mn thickness as below a critical temperature. The enhancement of the variation angle with the increase of Mn thickness follows the tendency of the finite-size effect of antiferromagnetism on interface exchange coupling. The flipping magnetization emerging coincidentally with the uncompensated-compensated transition of Mn magnetic surface indicates a frustration-induced biquadratic-type interface exchange coupling, and suggests a layered-like uncompensated AFM ordering for the Mn layer.

“…14 The in situ magnetic field H for MOKE measurements is provided by means of an electromagnet whose poles reach inside the UHV chamber. Careful calibration of the electromagnet and highly controlled MOKE experimental procedures allow one to reliably measure hysteresis loops with Ϯ0.4 Oe resolution in H. A sample morphology schematically sketched in the top part of Fig.…”

We have investigated the exchange bias ͑EB͒ in ultrathin epitaxial Cr/Fe/Ag͑001͒ nanopatterned bilayers characterized by atomic-scale-tailored interfaces consisting of nanoripples aligned along the ͓100͔ Fe direction. Precisely measuring the magnetic anisotropy of the system, we quantitatively characterized the energetics of the magnetization reversal in terms of domain-wall propagation in the Fe layer and discussed the influence of the interface structure in determining the exchange bias and promoting the domain-wall processes. We found no influence of the relative orientation of the field-cooling direction with respect to the nanoripple orientation in determining the EB magnitude, but we observed that the anisotropic morphology generates characteristic spin frustrations affecting the energetics of different domain-wall processes.

“…The experiments have been performed in an ultrahigh vacuum system with a base pressure <1 10 ÿ10 mbars, equipped with facilities for the growth and characterization of ultrathin magnetic films [11,18]. The chamber features the magneto-optical Kerr effect (MOKE), low energy electron diffraction (LEED) with spot profile analysis, and Auger electron spectroscopy (AES).…”

We have investigated the possibility of isolating the step-induced in-plane uniaxial magnetic anisotropy in Fe/Ag(001) films on which nanoscale surface ripples were fabricated by the ion sculpting technique. For rippled Fe films deposited on flat Ag(001), the steps created along the ripple sidewalls are shown to be the only source of uniaxial anisotropy. Ion sculpting of ultrathin magnetic films allows one to selectively study the step-induced anisotropy and to investigate the correlation between local atomic environment and magnetic properties.
