Magnetic properties of mixed spinel BaTiO3-NiFe2O4 composites
TL;DR: In this article, a compressive strain is developed in NiFe2O4 due to mutual structural interaction across the interface of NiFe 2O4 and barium titanate (BaTiO3) phases.

Optical and ferroelectric properties of ruthenium-doped BaTiO 3 nanocubes
TL;DR: In this paper, structural, optical, dielectric and ferroelectric properties of Ru-doped BaTi1−xRuxO3(x ǫ = 0.01, 0.03,0.05, 007, 010) nanocubes have been investigated.

Exchange bias effect in BiFeO3-NiO nanocomposite
Kaushik Chakrabarti,Babusona Sarkar,Vishal Dev Ashok,Kajari Das,Sheli Sinha Chaudhuri,Amitava Mitra,S. De +6 more
TL;DR: In this paper, the ferromagnetic ordering in pure BiFeO3 nanocrystals has been confirmed from X-ray diffraction and transmission electron microscope studies, showing that high Neel temperature (TN) of NiO leads to significant exchange bias effect across the NiO interface at room temperature.

G. Mohanto,A. Parihari,P. C. Rout,S. De,E. T. Mirgule,B. Srinivasan,K. Mahata,S. P. Behera,Mukesh Kumar Kushwaha,D. Sarkar,B. K. Nayak,A. K. Saxena,A. K. Rhine Kumar,A. Gandhi,Sangeeta,Nabendu Kumar Deb,P. Arumugam +16 more
TL;DR: In this article, the authors measured the neutron spectra at different excitation energies and found evidence for collective enhancement of the nuclear level density and its fadeout in Os and Pb nuclei.

Balaram Dey,C. Ghosh,Deepak Pandit,A. K. Rhine Kumar,S. Pal,V. Nanal,R. G. Pillay,P. Arumugam,S. De,Gurudutt Gupta,H. Krishnamoorthy,H. Krishnamoorthy,E. T. Mirgule,Surajit Pal,P. C. Rout +14 more
TL;DR: In this article, the authors reported the first observation of the Jacobi shape transition in the decay of giant dipole resonance (GDR) using high energy gamma-rays as a probe.
