ABSTRACTIn-situ scanning tunneling microscopy (STM). magneto-optical Kerr effect (MOKE) and Kerr microscopy are used to investigate the relations between structure, morphology, and magnetism in low-temperature (LT) grown Fe/Cu(100) films. At the spin reorientation thickness of ≈ 3.8 monolayers (ML) Fe/Cu(100) the coexistence of in-plane and out-of-plane magnetized domains is observed. For Fe thicknesses between 3.8 and 6 ML Fe/Cu(100). an irreversible spin reorientation from in-plane to out-of-plane can be induced by annealing up to 420 K. Annealing of LT-grown Fe/Cu(100) films is proposed to provide smooth surfaces for Cu/Fe/Cu(100) sandwich preparations.

ABSTRACTWe have characterized magnetization loops of epitaxially grown Gd (0001) films on W (110) in the temperature range 145≤T≤300K. This was accomplished by measuring magneto-optical Kerr loops in UHV, in the transverse geometry, using a 2×10-4 deg sensitivity differential detector and He-Ne laser light.Films grown in the Stranski-Krastanov (SK) Mode (growth temperature 400°C) and films grown in a Frank-van-der-Merwe (FM) like Mode (growth temperature 20°C) behave significantly differently. While the room temperature grown films (FM) show square hysteresis behavior only after an annealing cycle to at least 300°C, the higher growth temperature (SK) leads to highly remanent films in the as grown state.The hysteresis behavior of these films is most important in conjunction with recently reported spin-polarized photoemission results, which showed that the growth temperature and therefore the film morphology has a strong influence on the surface magnetic reconstruction of Gd (0001) [1].
