Enhancement of large magnetoresistances in ruthenocuprates by Ta substitution
Literature Information
A. C. Mclaughlin, L. Begg, A. J. McCue, J. P. Attfield
An unexpected enhancement of the large negative magnetoresistance (MR) observed in RuSr2Nd0.95Y0.15Ce0.9Cu2O10−δ up to −47% at 4 K and 9 T is evidenced upon dilution of the Ru magnetic order by substitution of Ta for Ru; this enhancement of −MR scales with the cell volume.
