  A signal crystal of NaGd(PO3)4 (NGP) was successfully grown with the solid-state reaction method under appropriate synthesis conditions. Structure refinements and the purity of the samples were determined by XRD patterns. It reveals that NaGd(PO3)4 compound crystallizes in the monoclinic system with P 21/n space group and with cell parameters a=7.174(1) Å, b=13.033(2) Å, c=9.781(1) Å, β=90.65(2)°, V=914.47(20) Å3 and Z=4. The IR and Raman spectra also indicated that the phosphoric polyhedra of NaGd(PO3)4 has a acyclic symmetry. Differential thermal analysis is given. This compound is thermally stable until 852°C. The magnetic susceptibilities of gadolinium polyphosphate as a function of temperature are reported along with corresponding magnetization measurements. This polyphosphate displays a paramagnetic response, without magnetic phase transitions,.. View More»
