Abstract : The pyrochlore was synthesized via a ceramic method using two different oxides (Er2O3 and TiO2). The compound was found to crystallize in the cubic system with the space group (No. 227). A magnetic study, carried out at 2 and 300 K under an applied magnetic field mu (0) H=0.05 T, has revealed a complex magnetic structure at low temperature. The effective paramagnetic moment , deduced from (chi-chi (0))(-1)=f(T) curve, was found by assuming a zero moment on the transition metal atom Ti4+. The paramagnetic Curie-Weiss temperature theta (CW)=-21.54 K, the nearest neighbor interaction J (nn) =-2.30 K, the classical nearest neighbor J (cl)=-8.65 K and the dipolar D (nn) =3.76 K interactions' values have revealed an antiferromagnetic behavior for Er2Ti2O7 compound at low temperature. We have also studied the effects of the magnetic field splitting of rare-earth atom Er3+ in the compound Er2Ti2O7 curved Arrott plots.
