Magnetic properties of (Y 1 - x Nd x ) 2 BaNiO 5 with x = 1 ; 0.25; 0.15; and 0.04 are investigated by means of specific heat, magnetic susceptibility, and spectroscopic measurements. We estimate a magnetic contribution of the neodymium subsystem into a total specific heat and magnetic susceptibilit...

Summary:Magnetic properties of (Y 1 - x Nd x ) 2 BaNiO 5 with x = 1 ; 0.25; 0.15; and 0.04 are investigated by means of specific heat, magnetic susceptibility, and spectroscopic measurements. We estimate a magnetic contribution of the neodymium subsystem into a total specific heat and magnetic susceptibility using spectroscopic data. We show that the nickel subsystem is intrinsically disordered in the whole temperature range studied, whereas the magnetization of the nickel chain segments contributes to the total magnetic susceptibility and specific heat at low temperatures.
