  Abstract  
  The EPR properties and magnetic susceptibility of pure and Yb3+ ion doped sodium rare-earths element double orthophosphates were investigated. The magnetic properties of the compounds obtained by hydrothermal and Pechini methods were compared. Their calcination at tempeartures: 120°C, 500°C, 700°C and 1100°C was carried out in order to describe phase structures evolving with increasing calcination temperature. EPR analysis allowed to find clear differences between the gadolinium ions arrangement in undoped and doped with ytterbium Na3Gd(PO4)2, obtained by hydrothermal and Pechini methods. It was possible by finding spin-Hamiltonian parameters calculated for some pure and ytterbium doped orthophosphates.
