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…
Improper Ferroelectricity in Helicoidal Antiferromagnet Cu3Nb2O8
G. Sharma, J. Saha, S. D. Kaushik +2
Cu3Nb2O8 is an unusual multiferroic compound that undergoes a series of magnetic ordering at low temperatures. Concurrent development of electric polarization has been reported at…
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…
Magnetic entropy change and critical exponents in double perovskite Y2NiMnO6
G. Sharma, T. S. Tripathi, J. Saha +1
We report on the magnetic entropy change and the critical exponents in the double perovskite manganite Y2NiMnO6 with a ferromagnetic to paramagnetic transition TC=85K. For a magnet…
Evidence for Multiferroic Characteristics in NdCrTiO5
J. Saha, G. Sharma, S. Patnaik
We report NdCrTiO5 to be an unusual multiferroic material with large magnetic field dependent electric polarization. While magneto-electric coupling in this two magnetic sub-lattic…
