I will show that by employing differe nt mechanisms to tune the magnetization tilting angle\, any magnetization orientation within the plane perpendicular to the step edges can be achiev ed. In particular\, increasing the Fe film thickness leads to the continuo us rotation of the magnetization easy axis toward the film surface and the sense of this rotation in uncovered films is opposite to that in films co vered with Au. Another tuning mechanism is provided by oscillatory changes of the tilting angle at low temperatures due to the formation of quantum well states in Fe films. The observed canting of magnetization will be exp lained within a phenomenological model by an interplay of the shape anisot ropy and two magnetocrystalline anisotropy terms\, perpendicular and step- induced anisotropies\, which results in an effective uniaxial magnetic ani sotropy. Finally\, I will show that the fitted thickness dependencies of t he anisotropy constants accurately reproduce experimental variations of th e tilting angle with both Fe and Au thicknesses as well as transient chang es of the magnetization orientation in ultrathin Fe films upon submonolaye r Au coverage\, observed with spin-polarized low-energy electron microscop y.\n\nCo-sponsored by: UCCS\n\nSpeaker(s): Marek Przybylski \, \n\nRoom: A 204\, Bldg: Osborn\, 1420 Austin Bluffs Pkwy\, Colorado Springs\, Colorado \, United States\, 80918 LOCATION:Room: A204\, Bldg: Osborn\, 1420 Austin Bluffs Pkwy\, Colorado Spr ings\, Colorado\, United States\, 80918 ORGANIZER:zcelinsk@uccs.edu SEQUENCE:0 SUMMARY:Tuning of Easy Magnetization Axis by Thickness\, Covering and Quant um Confinement URL;VALUE=URI:https://events.vtools.ieee.org/m/216634 X-ALT-DESC:Description: <br /><p style="text-align: justify\;"><span style= "font-size: 16.0pt\; font-family: 'Times New Roman'\,serif\;">I will prese nt a joint experimental and theoretical study that demonstrates how to eff iciently control a canted state of magnetization in Fe films grown on vici nal surfaces.
