The electrical resistivity and the Hall effect of gold, silver and copper were measured at low temperatures.The Hall effect of the gold sample which showed the minimum at 6°K in the resistivity-temperature curve was found to increase with temperature below 6°K.Since to electron mobility deduced from the resistivity and the Hall coefficient is nearly constant below 6°K, it is suggested that the resistance minimum of gold might be ascribed its origin to the change in the concentration of current carriers. On the other hand, the silver and copper samples which were measured showed the normal behaviour of electrical resistivity and the temperature independent Hall effect. In general, the Hall coefficients of these noble metals at low temperatures are found to have constant values which are about 20 per cent larger than at room temperatures, indicating that at intermediate temperatures (20°K300°K) the Hall effect is temperatures dependant.
