The rapidly solidified ribbon samples of the Pr9Fe58Co13Zr1Nb4B15 alloy subjected to short time annealing at temperatures ranging from 923 K to 1033 K were investigated. The phase analysis supported by the Rietveld refinement was used to identify the phase constitution. The results of Rietveld calculations were confirmed by transimission electron microscopy and M(T) studies. Measurement of recoil curves allowed the determination of switching field distributions and δ M plots for samples annealed at various temperatures.
