Magnetic properties of the ternary compounds Zr(Fe1-xCox)2 with the cubic Leves phase structure are calculated in the rigid band model. The concentration dependences of the magnetization, high-field susceptibility and electronic low-temperature specific heat coefficient are calculated at 0 K. The temperature dependence of the paramagnetic susceptibility is calculated by taking into account the effect of spin fluctuations. A good agreement between the calculated and observed results is obtained in the ferromagnetic region. A first-order transition from the ferromagnetic to paramagnetic state is shown to occur at x = 0.45.
