Upper critical fields Bc2(T) near Tc have been measured for the samples of Ba2YCu3Ox and Ba2GdCu3Ox. The upper critical field slope (dBc2dT)Tc and the upper critical field Bc2(O) have been calculated by using the least squares filling of straight line and using WHH expression in dirty limit respectively. The results show that Bc2(O) can be reach 114T and 127T for the samples of Ba2YCu3Ox and Ba2GdCu3Ox respectively. It is observed that there is a upwards curvature near Tc in the curves of B(T) vs.T. The main reason might be a proximity type effect in which a small amount of high Tc materials is able to raise the effective Tc of the samples, However such an effect could be suppressed at high field.
