Description: The temperature dependence of the electrical resistivity of the <math>Y(Fe_{1-x}Al_x)_2\,\!</math> system <math>(0.125 \leqq x \leqq 0.25)\,\!</math> was measured. This system exhibits a minimum at low temperatures for the concentration range where the phase diagram presents a spin glass-ferromagnetic transition. A negative temperature coefficient is observed at high temperatures for <math> x > 0.18\,\!</math> and was attributed to the high value of the electrical resistivity in this concentration range.
