J Alloys Compounds. 2001;323-324:710-30925-8388http://hdl.handle.net/2183/14023[Abstract] We have recorded the FTIR spectra of powder samples of Ln2−xSrxCoO4 (Ln=La, Nd) at room temperature. We have identified the infrared active modes (3A2u+4Eu), and analyzed how they change as a function of Ln and the Sr doping. We correlate the obtained results with structural data obtained from powder X-ray diffraction studies and with the electronic properties displayed by these samples.engLight absorption and reflectionMagnetically ordered materialsChemical synthesisCrystal structure and symmetryPhononsjournal articleopen access
