Resumo

The parameters of hyperfine interactions (hyperfine fields, isomer shifts, and quadrupole shifts) in Bi(_1–x)La_xFeO₃ (x = 0.1, 0.2) multiferroics are measured by Mössbauer spectroscopy at temperatures ranging from 5 to 850 K. The temperatures of magnetic and ferroelectric transitions are also determined.
