Abstract

Single crystals of Sr2 Ho Ru1-x Cux O6 (with x=0-0.2), measuring 2-3 mm across have been grown from PbO-Pb F2 based solutions in the temperature range of 1250-1150 °C. The crystals exhibit octahedral morphology and belong to the monoclinic space group P 21 n. While Sr2 HoRu O6 is found to be antiferromagnetic with weak ferromagnetism below 30 K, the solid solutions containing Cu exhibit a diamagnetic transition at 31 K which increases in magnitude and temperature with increasing Cu. Through a correlation of magnetic and calorimetric properties, these crystals are concluded to be spin-glass superconductors.
