[en] It is a known fact, that high temperature superconducting oxides show antiferromagnetic order of the CuO₂ plains as their main characteristic. This allows the use of techniques, which are common to Raman spectroscopy, for the detection of inelastic scattering of magnon pairs represented by a wide band centered around 2500 cm^-1. This communication presents the results of preliminary measurements of such excitations in Bi-2212 tablets which are nominally pure, semiconducting, and doped with Fe under a DC current at temperatures lower than T_c. Under these circumstances we find an increase in the full width half maximum of the approximately symmetrical band of two magnons in the tablet and a significantly higher intensity on the high frequency side. These measurements suggest that the carriers involved in the direct current might affect the exchange interaction by means of an electro-magnon interaction. (Author). 5 refs., 2 figs
