Charge stripes seen with X-rays in La1.45Nd0.4Sr0.15CuO4

Superstructure reflections due to the ordering of holes into stripes in La1 .45Nd0.4Sr0.15CuO4 have been studied with high energy X-ray diffraction. Th ese reflections have been observed clearly for the first time in a sample w hich is superconducting at low temperatures (T-c similar to 10 K). The stri pe peaks vanish above 62(5)X whereas the magnetic signal of the stripe orde ring which has been seen with neutrons before is already suppressed at simi lar to 45 K. Our results confirm that the ordering of spins and holes is dr iven by the charges as it is found in the case of La1.6-xNd0.4SrxCuO4 at th e doping level of x = 0.12.
