• The temperature dependence of magnetic properties of Ni_3Fe have been measured at a fixed state of order. Ni_3Fe is a characteristic example of the A_3B type ferromagnetic alloy undergoing an order-disorder transformation. Particular stress was placed on the change of magnetic properties at the order-disorder transformation temperature 490℃. Magnetization was measured with an astatic magnetometer equipped with an electric vacuum furnace enabling rapid heating of the sample. Magnetostriction was measured by a new apparatus designed to simplify manipulation of the sample at high temperatures. At a fixed state of order, the saturation magnetostriction was seen to decrease monotonically with temperature, whereas at a fixed temperature it was seen to increase with the formation of order. In particular, λ_s increases by 200%, from below 2・10^<-6> at the disordered state to 5.8・10^<-6> at the ordered state at the order-disorder transformation point.
