Single crys- tals were grown out of a FeAs self-flux using conventional high-temperature solution growth and characterized by X-ray diffraction, atomic force microscopy, and Raman. Raman spectra were obtained at room temperature and 77 K on ab - and a ( b ) c -planes. Two offour phonon modes allowed by sym- metry were found and identified. It was observed that the scattering intensity of A 1g mode and the frequencies of the A 1g and B 1g phonons are dependent upon doping of Mn. The dependence of scattering intensity and frequency of A 1g mode on Mn doping might indicate that the Mn ion also oc- cupies the As site. 2015 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46438835008 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2 Vol.45 |
