Effect of phase separation induced supercooling on magnetotransport properties of epitaxial La5/8-yPryCa3/8MnO3 (y~0.4) thin film
Sandeep Singh, Geetanjali Sharma, P. K. Siwach +3
Thin films of La5/8-yPryCa3/8MnO3 (y~0.4) have been grown on single crystal SrTiO3 (001) by RF sputtering. The structural and surface characterizations confirm the epitaxial nature…
Resistivity minimum in strongly phase separated manganite thin films: impact of intrinsic and extrinsic perturbations
Vasudha Agarwal, Geetanjali Sharma, P. K. Siwach +2
The origin of the resistivity minimum observed in strongly phase separated manganites has been investigated in single crystalline thin films of LPCMO (x~0.42, y~0.40). The antiferr…
Ferromagnetism, insulator-metal transition and magnetotransport in Pr0.58Ca0.42MnO3 films: role of microstructural perturbations
Vasudha Agarwal, P. K. Siwach, G. D. Varma +3
Magnetic and magnetotransport properties of oriented polycrystalline Pr0.58Ca0.42MnO3 thin films prepared in flowing oxygen and air ambient has been investigated. The magnetic grou…
Crossover from charge order to strain glass in phase separated manganite thin films: Impact of thermal cycling and substrate induced strain
Vasudha Agarwal, P. K. Siwach, V. P. S. Awana +1
The magnetic and magnetotransport properties of single crystalline La1-x-yPryCaxMnO3 (x=0.42, y=0.40) thin films (~140 nm) deposited on (110) oriented LaAlO3 and SrTiO3 substrates…
Comparative study of magnetic and magnetotransport properties of Sm0.55Sr0.45MnO3 thin films grown on different substrates
Manoj K. Srivastava, Sandeep Singh, P. K. Siwach +4
Highly oriented polycrystalline SSMO thin films deposited on single crystal substrates by ultrasonic nebulized spray pyrolysis have been studied. The film on LAO is under compressi…
Impact of size mismatch induced quenched disorder on phase fluctuation and low field magnetotransport in polycrystalline
Manoj K. Srivastava, Ravikant Prasad, P. K. Siwach +2
We report the magnetic and electrical transport properties of the bulk polycrystalline NGSMO (x ~ 0.0, 0.04, 0.08, 0.12, 0.16, 0.20, 0.25, 0.30, 0.35 and 0.42) synthesized by solid…
