With precise measurements at magnetic 6elds well above those required for saturation, it is shown thatthe Hall electric 6eld per unit current density consists of two distinct parts. Its value averaged betweenpoles is given by ROH+R&M, where H and j/I are the magnetizing force and average intensity of magnetization,respectively. in the sample.The value Eo=—0.611X10 ~ volt-cm/amp. -oersted indicates 1.16 s-band electrons with no d-bandconduction, 0.6 s-band electrons with 30 percent d-band conduction, or something intermediate betweenthese two.The value R&=-74.9X10 "volt-cm/amp. -oersted suggests the existence of a very large average magnetic6eld acting on the conduction electrons. An explanation for this is suggested.
