Critical small-angle neutron scattering has been performed on (Er{sub {ital x}}Nd{sub 1{minus}{ital x}}){sub 2}Fe{sub 14}B hard intermetallics around the spin reorientation transition (SRT) temperatures, {ital T}{sub SR}. The measured scattered intensities show squared Lorentzian type behavior (for {ital k} {le} 12 {times} 10{sup {minus}3} A{sup {minus}1}) and the magnetic correlation lengths show well defined anomalies at {ital T}{sub SR}, related to the scattering within the magnetic domain walls, which transform at the SRT.
