Temperature dependence of the electrical resistivity and the galvanomagnetic effect for amorphous rare earth-transition metal ferrimagnetic films between 1.5K and 700K has been studied. Thc absolute value of resistivity is about 270-400 μΩ·cm and the temperature coefficient of resistivity is negative and 10-4/K for Fe alloys and 10-5/K for Co alloys. The temperature characteristic of resistivity is divided into two regions. The logarithmic temperature dependence is dominant from 1.5K to 35K and the square dependence from 50K to 340K. The logarithmic temperature dependence disappears after annealing (1/2 hour at 700K). The square dependence is characterized by the resistivity minimum at about 340K.The transverse magnetoresistance effect decreases with increasing temperature and exhibits the minimum value near the compensation temperature. The electrical resistivity changes about 2.5% and the magnetoresistance effect about 0.01% over the range from 4.2K to 300K. This result shows that the number of domain walls makes very small contribution to the temperature dependence of
