Understanding the multiple magnetic structures of the intermetallic compound NdMn1.4Co0.6Si2
Madhumita Halder, A. K. Bera, Amit Kumar +2
Magnetic phases for the intermetallic compound NdMn1.4Co0.6Si2 have been investigated at various temperatures by dc magnetization, neutron diffraction and neutron depolarization. O…
Microstructural Evolution of Charged Defects in the Fatigue Process of Polycrystalline BiFeO3 Thin Films
Qingqing Ke, Amit Kumar, Xiaojie Lou +4
Fatigue failure in ferroelectrics has been intensively investigated in the past few decades. Most of the mechanisms discussed for ferroelectric fatigue have been built on the "hypo…
Effect of Zn doping on the Magneto-Caloric effect and Critical Constants of Mott Insulator MnV2O4
Prashant Shahi, Harishchandra Singh, A. Kumar +5
X-ray absorption near edge spectra (XANES) and magnetization of Zn doped MnV2O4 have been measured and from the magnetic measurement the critical exponents and magnetocaloric effec…
Electronic structure and stability of hydrogen defects in diamond and boron doped diamond: A density functional theory study
Ashutosh Upadhyay, Akhilesh Kumar Singh, Amit Kumar
Isolated hydrogen and hydrogen pairs in bulk diamond matrix have been studied using density functional theory calculations. The electronic structure and stability of isolated and p…
Carrier type modulation in current annealed graphene layers
Pawan Kumar, Amit Kumar
We report on the electrical properties of current annealed graphene and few layer graphene devices. It is observed that current annealing for several hours results the n-type dopin…
