In this work, we synthesized the Pr1-xSrxMnO3 (x = 0.2, 0.3 and 0.5) samples via improved chemical co-precipitation method and studied their structural, magnetic and magnetotransport properties. XRD results show that the unit cell parameters & cell volume decrease as we increase the Sr concentration from x=0.2 to x=0.5. Temperature dependence magnetization measurements indicate that all sample show the paramagnetic to ferromagnetic transition and the Curie temperature increases from 130 to 292 K for the sample x=0.2 to x=0.5. Moreover, the maximum value of magnetization has been observed for the composition with x=0.3. Temperature dependence electrical resistivity measurements show the metal to insulator transition at 102 and 143 K, respectively for sample x = 0.2 & 0.3. However, sample x= 0.5 shows the insulating behavior in the whole measured temperature range (80-300 K). Furthermore, the magnetoresistance studies show that the maximum (MR) is observed for the composition, x=0.3..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
