| 英文摘要 | Recent progress of the soft x-ray magnetic circular dichroism (xmcd) techniques and relevant applications at beamline 4b7b in beijing synchrotron radiation facility are reported here. the key progress of the xmcd techniques include i) improvements in the accuracy and sensitivity of xmcd measurements by fast-reversing magnetic field with electromagnet, and ii) establishment an angle-dependent experimental method for obtaining the magnetic anisotropy information. these techniques have been applied to investigate the interface ferromagnetism and magnetic anisotropy of two mn-based materials, i.e. fe/(ga, mn) as and la2/3sr1/3mno3/srtio3 bilayer heterostructures. an enhanced xmcd signal has been observed at the fe l-2,l-3-edges whereas a relative small but unambiguous mn xmcd signal with opposite sign has been detected which indicates an antiferromagnetic coupling at fe/(ga, mn) as interfaces. a comparative study of the stoichiometric and nonstoichiometric la2/3sr1/3mno3/srtio3 bilayers clearly demonstrates that the oxygen vacancies degrade the magnetic properties of the perovskite manganese oxide film. these achievements benefit from the established field-reversal and angle-dependent xmcd techniques, which will make it possible to extend the research field of our devices from ferromagnetic to paramagnetic or diluted magnetic semiconductor system. |
