High-temperature insulating ferromagnetic state in charge-disproportionated and spin-state-disproportionated strained SrCoO2.5 thin film

Autor: Sourav Chowdhury, Anupam Jana, Ritu Rawat, Priyanka Yadav, Rajibul Islam, Fei Xue, A. K. Mandal, Sumit Sarkar, Rajan Mishra, R. Venkatesh, D. M. Phase, R. J. Choudhary

Publikováno v: APL Materials, Vol 12, Iss 5, Pp 051129-051129-9 (2024)

Ferromagnetic insulators (FMIs) have widespread applications in microwave devices, magnetic tunneling junctions, and dissipationless electronic and quantum-spintronic devices. However, the sparsity of the available high-temperature FMIs has led to th

Synthesis of Cu2O from CuO thin films: Optical and electrical properties

Autor: Dhanya S. Murali, Shailendra Kumar, R. J. Choudhary, Avinash D. Wadikar, Mahaveer K. Jain, A. Subrahmanyam

Publikováno v: AIP Advances, Vol 5, Iss 4, Pp 047143-047143-5 (2015)

Hole conducting, optically transparent Cu2O thin films on glass substrates have been synthesized by vacuum annealing (5×10−6 mbar at 700 K for 1 hour) of magnetron sputtered (at 300 K) CuO thin films. The Cu2O thin films are p-type and show enhanc

Correlation between spin–phonon coupling and magneto-electric effects in CoFe2O4/PMN-PT nanocomposite: Raman spectroscopy and XMCD study

Autor: Anju Ahlawat, Azam Ali Khan, Pratik Deshmukh, Mandar M. Shirolkar, A. K. Sinha, S. Satapathy, null V.G.Sathe, R. J. Choudhary

Publikováno v: Journal of Materials Science: Materials in Electronics. 33:19766-19778

We have investigated the coupling of lattice with spin via strain interactions in the CoFe2O4/PMN-PT composite system. X-ray diffraction and Raman spectroscopic studies illustrate a remarkable modification in CoFe2O4lattice across Curie temperature (
