|Issue Date:||7-May-2013||Citation:||Kumar, P., Aparnadevi, M., Mahendiran, R. (2013-05-07). Interplay of 3d-4f exchange interaction in Pr0.5-xNd xSr0.5CoO3. Journal of Applied Physics 113 (17) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.4798503||Abstract:||We have investigated electrical and magnetic properties of Pr 0.5-xNdxSr0.5CoO3 (x 0.0, 0.1, 0.2, 0.3, and 0.5) samples. Upon cooling, field-cooled magnetization of Pr 0.5Sr0.5CoO3 shows an anomalous increase at TA 120 K within the ferromagnetic state coupled structural and magnetic anisotropy transitions. This anomaly shifts to 88 K for x 0.1 but its magnetization starts decreasing below Tferri 35 K, where T ferri signals the onset of ferrimagnetic interaction between Nd(4f) and Co(3d) moments. The structural transition is absent in x 0.2. While the ferromagnetic Curie temperature decreases with increasing Nd content by 8 K, Tferri increases from 35 K for x 0.1 to 80 K for x 0.5. The ferrimagnetic interaction does not affect the dc resistivity. All the studied samples are metallic and magnetoresistance decreases from -6.7 for x 0 to -0.7 for x 0.5. © 2013 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/98764||ISSN:||00218979||DOI:||10.1063/1.4798503|
