The magnetic behavior of TiBe2 is found to be similar to that of strongly enhanced paramagnets like Pd and NiaGa. The susceptibility curves x(H, T = 0) and x(T, H = 0) both go through a smooth maximum, at 55 kOe and 10 K, respectively, which might be due to the electron-electron interaction. For TiBe2_xCu x compounds the transition from paramagnetism to ferromagnetism is analyzed, starting from Arrott plots of the magnetization. A critical concentration Xcr = 0.155 -+ 0.005 is obtained. The Stoner-Edwards-Wohlfarth model of itinerant-electron magnetism is well followed near Xcr. The low temperature behavior of the specific heat of TiBe 2 is tentatively ascribed to the effect of the electron-phonon interaction on the electronic specific heat coefficient 3'.
