Defect mediated mechanism in undoped, Cu and Zn-doped TiO2 nanocrystals for tailoring the band gap and magnetic properties

Akshay, V R; Arun, B; Dash, S; Patra, A K; Mandal, G; Mutta, G R; Anupama, C; Vasundhara, M (Royal Society of Chemistry, 2018-12-17)

Oxide based dilute magnetic semiconductor materials have been of great interest over the years due to their potential use in spintronic devices. However, the variations in the magnetic behavior of the materials have raised ...
E ects of Mn site substitution on magnetic ordering ff and critical behavior in Nd0.67Sr0.33MnO3 manganite

Arun, B; Suneesh, M V; Sudakshina, B; Akshay, V R; Chandrasekhar, K D; Vasundhara, M (Elsevier, 2018-08)

In this study, we investigated the structural, magnetic order, and critical exponent behaviors for substitutions of 3d transition elements (Cr, Fe, and Co) at the Mn site in Nd0.67Sr0.33MnO3. Rietveld refinement confirmed ...
Investigation on the Structural, Magnetic and Magnetocaloric Properties of Nanocrystalline Pr-Deficient Pr1−xSrxMnO3−δ Manganites

Arun, B; Athira, M; Akshay, V R; Sudakshina, B; Mutta, G R; Vasundhara, M (Elsevier, 2018-02-15)

We have investigated the structural, magnetic and magnetocaloric properties of nanocrystalline Prdeficient Pr1 xSrxMnO3 d Perovskite manganites. Rietveld refinement of the X-ray powder diffraction patterns confirms that ...
Observation of enhanced magnetocaloric properties with A-site deficiency in La0.67Sr0.33MnO3 manganite

Arun, B; Akshay, V R; Vasundhara, M (Royal Society of Chemistry, 2018-10-09)

In this paper, we have studied the effect on the structural, magnetic and magnetocaloric properties of La and Sr-deficiencies in the La0.67Sr0.33MnO3 compound. Rietveld refinement of the X-ray powder diffraction patterns ...
Observation of Optical Band-Gap Narrowing and Enhanced Magnetic Moment in Co-Doped Sol−Gel-Derived Anatase TiO2 Nanocrystals

Akshay, V R; Arun, B; Mandal, G; Mutta, G R; Chanda, A; Vasundhara, M (American Chemical Society, 2018-11-08)

The magnetic behavior of TiO2 and doped TiO2 nanocrystals has been a challenge due to the unambiguous nature of defects present in oxide semiconductors. Here, a simple, low-temperature sol–gel method is developed for the ...
Structural and Magnetic Behavior of (Ni, Cu) Substituted Nd0.67Sr0.33MnO3 Perovskite Compounds

Arun, B; Sudakshina, B; Akshay, V R; Devi Chandrasekhar, K; Yang, H D; Vasundhara, M (AIP, 2018-05-08)

Structural and magnetic phase transition of Ni and Cu substituted Nd0.67Sr0.33MnO3 perovskite compounds have been investigated. The Rietveld refinement of X-ray powder diffraction patterns confirms that both compounds ...
Surfactant-Induced Structural Phase Transitions and Enhanced Room Temperature Thermoelectric Performance in n‑Type Bi2Te3 Nanostructures Synthesized via Chemical Route

Akshay, V R; Arun, B; Suneesh, M V; Vasundhara, M (American Chemical Society, 2018-06)

A systematic study of surfactant-assisted aqueous-based low-temperature chemical method for the synthesis of different phases of Bi−Te-based nanostructures with different morphologies ranging from nanocrystals to nanoro ...
