Observation of Enhanced Magnetic Entropy Change Near Room Temperature in Sr-site Deficient La0.67sr0.33mno3 Manganite

B, Arun; V R, Akshay; M, Vasundhara (Royal Society of Chemistry, 2019-07-24)

The effect of Sr-site deficiency on the structural, magnetic and magnetic entropy change of La0.67Sr0.33−yMnO3−δ (y = 0.18 and 0.27) compounds was investigated. The compounds were prepared by the conventional solid-state ...
Significant Reduction in the Optical Band-gap and Defect Assisted Magnetic Response in Fe-doped Anatase Tio2 Nanocrystals as Dilute Magnetic Semiconductors

V R, Akshay; B, Arun; G, Mandal; A, Chanda; M, Vasundhara (Royal Society of Chemistry, 2019-03-12)

Here, we have employed a low-temperature sol-gel route for developing functional semiconducting, Fe-doped anatase TiO2 nanocrystals. Detailed investigation of X-ray powder diffraction patterns confirms the anatase phase ...
Visible Range Optical Absorption, Urbach Energy Estimation and Paramagnetic Response in Cr-doped Tio2 Nanocrystals Derived by a Sol-gel Method

V R, Akshay; B, Arun; G, Mandal; M, Vasundhara (Royal Society of Chemistry, 2019-05-20)

We have carried out a detailed study of the morphological, structural, optical and magnetic properties of Cr doped TiO2 nanocrystals with doping concentrations varying from 3 to 12 atomic weight%. The results obtained from ...
