The temperattare dependence of the electrical res;istivity of GdNi single crystalhas been iztvestigated in the temperature range 4.2-?300 K. The Curie temperatureT. was 7241 K. The resistivity was proporjion?tl to T' below Tt with largecoefficients 6.1x1O-'O'cm"K=' for a-axis arnd 5.4x10 '0'cm'K-" for6-axis. The resistivity p.... due to magnetic disorder for Z>-axis was about ten timeslarger than for a- and c-axes. This anisotropy was interpreted as the differenceof the effective mass of conduction electrons. The magnetic exchange interactionJ.(( was estimated as 0.07 eV on the basis of the localized magnetic model.
