Abstract
Electrical resistance and magneto-resistance of gamma brass were measured at liquid helium, liquid nitrogen and room temperature. Moreover, Hall coefficient and thermoelectric power of gamma brass were measured at room temperature. Data of the electrical resistance are presented for several samples having various concentrations. In the relation between specific resistivity and concentration, a minimum occurs at about 34 wt.% copper in the curve of resistivity v s . concentration. The value of the Hall coefficient and of the thermoelectric power are comparable to the values of pure metals. The magneto-resistance is small at room temperature but becomes large at liquid helium temperature. Differences of the physical properties between gamma brass and bismuth are discussed.
