Abstract

We have performed ultrahigh vacuum scanning tunneling microscopy measurements at room temperature on (Nd_0.33Eu_0.38Gd_0.28)Ba₂Cu₃O_y (NEG123) crystals grown by an oxygen controlled melt growth process. Two characteristic nanostructures, namely, modulation and island structures have been observed on a cleaved surface of the NEG123 with high J_c and high irreversible field H_irr higher than 10 T at 77 K. These structures may be associated with an element substitution and the good J_c-B property.
