Non-monotonic magnetic anisotropy behavior as a function of adsorbate coverage in Fe ultrathin films near the spin reorientation transition

Abstract

Carbon monoxide (CO) adsorption on ultrathin fcc Fe films is known to result in the rotation of magnetization from out-of-plane to in-plane.

Structural characterization and electronic properties of Ni/rubrene bilayers with alternative stacking sequences

“…24 The adsorbed carbon monoxide (CO) on ultrathin face-centred cubic (fcc) Fe films changed the direction of magnetization from in-plane (IP) to out-of-plane (OP). 25 Rubrene is one of the OSCs that shows numerous intriguing electrical properties, including a high mobility, long-excitation lifetime, and spin-relaxation length. [26][27][28] The most prominent evidence for developing spintronic devices was the spinrelaxation length of amorphous rubrene, which was determined as 46 nm at 100 K and 132 nm at 300 K. 28 Magnetoresistance measurements of rubrene indicated that rubrene is the most promising organic material for showing spin-transport characteristics for the fabrication of organic spin valve devices.…”

Spin- and angle-resolved inverse photoemission setup with spin orientation independent from electron incidence angle

“…A deep understanding of these systems often requires using a spin-polarized electron beam as a probe. Spin-polarized electron sources are essential, for instance, for spin-polarized low-energy electron microscopy (SPLEEM) [14][15][16] or spin-polarized inverse photoemission spectroscopy (SPIPES), which is the most direct technique to determine unoccupied electronic states with kresolution [17][18][19][20][21][22] and spin-resolution [23][24][25] .…”

Enhancing Electron Correlation at a 3d Ferromagnetic Surface

“…For example, in ultrathin FM films, CO, fullerene and other molecules enable the steering of the magnetization direction. [ 6,7 ] The adsorption of a π‐conjugated organic molecule on a ferromagnetic substrate locally increases the strength of the magnetic exchange interaction between its underlying magnetic atoms, thus leading to magnetic hardening. [ 8,9 ] Chemisorption of oxygen on Fe induces a strong Dzyaloshinskii–Moriya interaction, [ 10 ] while a hydrogenated Fe double layer on an Ir(111) substrate supports the formation of magnetic skyrmions.…”
