The Hall coefficient R(H) and the thermal conductivity kappa have been
measured for Cu-1234 superconductors. From the relation between the c
arrier concentration and the T-c, the highest T-c in the Cu-1234 syste
m seems to be about 126 K at the Hall number of similar to 0.2/CuO2. T
he temperature dependencies of rho similar to T, R(H) similar to 1/T a
nd cot theta = alpha T-2 (theta:Hall angle) were observed, and were si
milar to that of other hole-type cuprate oxide superconductors. The te
mperature dependence of kappa observed in Cu-1234 was somewhat unusual
and is discussed in comparison with kappa of YBCO and Hg-1234.
