The flux pinning behaviour of ternary melt-processed (Nd-Eu-Gd)Ba2Cu3Oy superconductors is studied with various second-phase defect concentrations using magnetotransport and magnetization measurements. A pronounced field-induced bump feature in the resistivity was observed. The dissipation was found to be thermal activation type. The current-voltage (I-V) characteristics over the whole transition temperature regime show a linear flux-flow type behaviour at high fields that favours an increase in viscosity in the liquid phase. However, I-V curves show a change of curvature at low field. The Nd/Ba substitution sites along with second-phase particles refined by the addition of a small amount of Pt are basically responsible for high flux pinning.
