Abstract
X-ray structural analysis of Hg0.7Cr0.3Sr2CuOy (nominal composition) w as done by Rietveld technique. The actual composition of the system an d the position of the ions obtained from the analysis will be presente d. The c-axis of this system is 0.9 A less than that of HgBa2CuO4+delt a. The T-c value obtained from resistivity measurement is similar to 5 1 K. The Hall angle cot O-H (rho/BR(H)) shows a T-2 temperature depend ence. Thermoelectric power is positive and large, indicating that the system is in the underdoped region.
