An Investigation Of The Ferromagnetic Insulating State Of Manganites
(2010-09-22)
Electrical conductance in the ferromagnetic insulating (FMI) phase of manganites has been experimentally investigated. The investigations were performed on single crystals of compositions La0.82Ca0.18MnO3 and Nd0.7Pb0.3MnO3. ...
Spatially Resolved Studies Of Electronic Phase Separation And Microstructure Effects In Hole Dopped Manganites
(2010-08-17)
The main focus of this thesis is in understanding the role of phase separation and microstructure in determining the physical properties of manganites. We also aim to be able to tune certain material properties using ...
Magnetization, Magnetotransport And Electron Magnetic Resonance Studies Of Doped Praseodymium And Bismuth Based Charge Ordered Manganites
(2010-09-06)
Studies on perovskite rare earth manganites of general formula R1-xAxMnO3 (where R is a trivalent rare earth ion such as La3+, Pr3+ etc. and A is a divalent alkaline earth ion such as Ca2+, Sr2+, Ba2+, have been a very ...
Orbital Evolution And Super-Orbital Flux Variations In X-ray Binary Pulsars
(2010-08-23)
X-ray binaries are binary stellar systems containing a compact object and a normal companion star which are gravitationally bound and rotate about a common center of mass. The compact object accretes matter from the companion ...
Dynamics, Order And Fluctuations In Active Nematics : Numerical And Theoretical Studies
(2010-08-24)
In this thesis we studied theoretically and numerically dynamics, order and fluctuations in two dimensional active matter with specific reference to the nematic phase in collections of self-driven particles.The aim is to ...
Phase Behaviour & Dynamics Of An Agitated Monolayer Of Granular Rods
(2010-10-05)
In this thesis we have explored the no equilibrium phase behavior and dynamics of an agitated monolayer of macroscopic rod-like particles. The main objective of this thesis was to highlight the ways in which even the ...
Investigation Of Damage Process In Current Stressed Metal Film Using Noise Spectroscopy, Scanning Thermal Microscopy And Simulation Studies
(2010-09-27)
Reliability, besides the performance, is one of the important key factors of success of any technology. While a product should perform at best as desired, it must also be capable of working for intended period of life ...
Graphene And Carbon Nanotubes : Field Induced Doping, Interaction With Nucleobases, Confined Water And Sensors
(2010-12-08)
This thesis presents experimental and related theoretical studies of single layer graphene, bilayer graphene and single walled carbon nanotubes. The thesis is divided into three parts; the first part describes the phonon ...
Development And Optimization Of A Microchip PCR System Using Fluorescence Detection
(2011-02-21)
Microfabricated thermal cyclers for nucleic acid amplification by using polymerase chain reaction (PCR) have been demonstrated by several groups over the last decade, with improved cycling speed and smaller volumes when ...
Separated Local Field NMR Spectroscopy In Partially Ordered Systems - New Methodologies And Applications
(2010-09-06)
Dipolar couplings are one of the major source of structural information. Due to their dependence on the distance between the nuclei and the angle of orientation of the dipolar vector with respect to the magnetic field, ...
