Abstract

The influence of local moment magnetism on the boron isotope effect of T_c was studied on single crystals of ErNi₂B₂C. Values of the partial isotope effect exponent of α_B = 0.10 ± 0.02 and α_B = 0.10 ± 0.04 and were obtained based on two different criteria applied to extract T_c. No significant change in the partial isotope effect exponent compared to the ones obtained for LuNi₂B₂C was observed. Based on this result, we conclude that pair-breaking due to the Er local magnetic moment appears to have no detectable influence on boron isotope effect of T_c.
