AbstractThe interfacial regimes of cobalt/pentacene/cobalt (Co/Pc/Co) trilayers were emulated through the ultrathin pentacene/cobalt (Pc/Co) and cobalt/pentacene (Co/Pc) bilayers. Employing the magneto-optical Kerr effect (MOKE) measurement, we found the coercivity of Co bottom film in a thickness of 3.4 nm experienced a slight reduction upon the adsorption of Pc molecules. For the bilayers prepared with reversed order of deposition, the Co film deposited on a 6.4 nm Pc layer showed no observable ferromagnetic order at room temperature until its thickness reached 3 nm. After the onset of magnetic order, the x-ray images acquired on Pc/Co revealed a complicated magnetization patterns comparing to those observed on Co/Pc bilayers. Because the spin-polarized carriers will interact with the environment along their transport path, the presence of a non-magnetic layer and the occurrence of complicated domain structures suggested the spin-polarized carriers would experience a greater disturbance on their spin coherence when crossing the Pc/Co interface.

Magneto Optical Kerr Effect

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].
