The magnetic and electrical properties of polycrystalline YBaCuO prepared by sintering various size of powders were examined by DC four-probe method and vibrating sample magnetometer(VSM). As magnetic properties, initial magnetic curves and hysteresis curves were measured and gradients of initial magnetic curves were calculated. Effects of shielding magnetic field were studied with YBaCuO pellets of 1 inch in diameter and 1 mm in thickness by hall generator(F.W.BELL) at DC magnetic field bellow
