We report the magnetization M as a function of magnetic field H at T=77 K for semiconducting Y1Ba2Cu3O6+x with x<0.5. For x=0 and T=77 K, there is a superlinear dependence of M on H, suggestive of spin-flop of the canted component of Cu++ on the CuO2 plane at a critical field. A strong hysteresis effect has been observed in M(H), indicative of first order transition at a critical field for the x=0 compound. For Y1Ba2Cu3O6+x samples of x=0.25 and 0.34, M is sublinear with H, in agreement with the presence of ferromagnetically ordered regions due to oxygen doping.
