We have measured the thermal conductivity ~: of bulk YBa2Cu40 s (1-2-4) between 30 and 310 K and at pressures p up to 1 GPa. At p = 0, ~: = 10 Wm-IK -1 near 100 K, twice that of sintered YBa2Cu3OT. s (1-2-3). ~Β’ also decreases with increasing T more rapidly than in 1-2-3, to 7.4 Wm'IK "1 at 300 K. U
