Abstract :
The author is investigating the influence on properties of vacuum-deposited thin films of organic dyes prepared applying magnetic fields. In spite of weak magnetic field intensity (0.1~0.3 T), the effect of magnetic field could be observed in PL spectra, X-ray diffraction pattern and IR-RAS spectra on p-quaterphenyl (4PO), 10,10´-Bianthrone (BA) and quinquethiophene (5T). Although the orientation of 4PO molecules is reduced by the application of magnetic field during growth, those of BA and 5T molecules are enhanced. When a magnetic field strength is weak, the magnetic orientation of organic molecule needs the magnetic anisotropy of molecule
