Exploration of multiferroicity, emergence of exchange bias effect and glassy magnetism in doped hexagonal rare-earth manganites
In recent days, the need for device miniaturization has led to immense research activities in the field of material science. It has become essential to discover and design new materials or to modify the existing materials ...
Studies of X-Ray Transients and a Future X-Ray Sky Monitor
For this thesis we studied X-ray transients. In addition we also studied some methods to study these transients, both observationally and in terms of the instrument used.
The first transient studied is a black hole binary ...
1H-NMR Study of Proton Glasses - Nuclear Spin Lattice Relaxation in BPxBPI(1-x) and BPxGPI(1-x) - Effects of Disorder on the Proton Group Dynamics
Mixed systems made from a combination of ferroelectric (FE) and antiferroelectric (AFE) compounds, exhibit various effects of disorder in different temperature regions. The kind of effects observed, depend on the technique ...
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ...
Study of the Thermoelectric Properties of RxCo4Sb12 (R=In, Ba) with InSb/GaSb Nano Inclusions
Almost 80% of the world’s energy needs depend on oil, coal and natural gases. Use of natural gases, fossil fuels emit a large amount of CO2 to the earth’s atmosphere, which causes the greenhouse effect and results in an ...
Effect of a fast flux line on the coherence of 3D transmon qubits
With the development of the science and technology, the quantum computers are becoming
the possible key to reveal new breakthroughs. Unlike the classical computers, where we
have classical bits (0or1), in quantum computation ...
Study of Exciton Dynamics in MoS2 Monolayer and MoS2-QD Heterostructure
The recent studies of two-dimensional semiconductors (2D) and their hybrid structure with zero-dimensional (0D) semiconductors have led to discovering of many fascinating properties that are absent in their bulk counterparts. ...
Study of Thermoelectric Transport Properties of Doped and Vacancy Induced BiCuSeO
About 70% of the heat generated for energy production is wasted and thermoelectric generators can capture this waste heat and convert it into useful electricity. The stability at high temperature in the ambient atmosphere ...
Exploring Electron Bubbles in Liquid Helium using Cavitation
An electron entering liquid helium experiences a repulsive potential of 1 eV. This originates in the interaction between the injected electron and electrons of the closed shells of helium atoms through Pauli exclusion ...
Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rare-earth manganites with the general formula T1xDxMnO3 where `T' is a trivalent
rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion,
e.g Ca2+; Sr2+;Ba2+ etc. display various ...
