Abstract

The effect of rare earth ion (RE = Er³⁺, Tb³⁺, Ho³⁺) substitution in Pr_0.74Sr_0.26MnO ₃ (PSMO(0.26)) on the magnetic and transport properties is reported. It is found that even for a small concentration of substitution of Pr ³⁺ ions by Er³⁺, Tb³⁺, or Ho³⁺ ions there is a significant change in the transport and magnetic properties compared to the parent compound Pr_0.74Sr_0.26MnO₃. The observed changes are attributed to the increase in the average A-site disorder upon substituting smaller ions (ionic radius of Er³⁺ = 1.062 Å, Ho³⁺ = 1.072 Å, Tb³⁺ = 1.095 Å) in place of bigger Pr³⁺ ion (ionic radius = 1.179 Å). The Ho³⁺ substituted sample was found to behave anomalously when compared to the other two rare earth ion-substituted (Tb³⁺ and Er³⁺) samples. Such anomalous behaviour could most likely be caused by the magnetic coupling of the Ho and Mn ions.
