Аннотация: The magnetic structure of the mixed rare-earth system PrxY1-xFe3(BO3)(4) has been studied by elastic neutron powder diffraction and magnetic measurements. A spin reorientation from easy axis to easy plane occurs in the concentration range x = 0.67-0.45 through the formation of inclined magnetic structures. The inclination of the FeПоказать полностьюmoments from the basal plane depends on the Pr content and ranges from 67(2)degrees for x = 0.67 to 16(4)degrees for x = 0.45 at T = 3K. A nonmonotonic change of the inclination angle with temperature is found for all compounds but there is no sign of a spontaneous spin reorientation in the temperature range of magnetic order. An approach based on a crystal-field model for the Pr3+ ion and on the molecular-field approximation is used to describe the magnetic characteristics of the system PrxY1-xFe3(BO3)(4). A good agreement between the experimental and calculated temperature dependences of the magnetic susceptibilities and the angle of inclination of Fe moments from the basal plane has been achieved.
