Magnetic and Magnetotransport Studies in Transition Metal Oxides : Role of Competing Interactions
(2018-04-12)
There was a fame time for silicon in condensed matter physics, then the graphene era came and now topological insulators are gaining lot of attention, but magnetism in condensed matter physics has remained always fascinating ...
NMR Methods For The Study Of Partially Ordered Systems
(2016-11-16)
The work presented in this thesis has two parts. The first part deals with methodological developments in the area of solid-state NMR, relevant to the study of partially ordered systems. Liquid crystals are best examples ...
Investigations Of Magnetic Anisotropy In Ferromagnetic Thin Films And Its Applications
(2016-02-17)
Physical systems having dimensions smaller than, or of the same order of magnitude as, the characteristic length scale relevant to a physical property are referred to as mesoscopic physical systems. Due to the dimensions ...
Optimization Of NMR Experiments Using Genetic Algorithm : Applications In Quantum Infomation Processing, Design Of Composite Operators And Quantitative Experiments
(2017-05-21)
Genetic algorithms (GA) are stochastic global search methods based on the
mechanics of natural biological evolution, proposed by John Holland in 1975. Here
in this thesis, we have exploited possible utilities of Genetic ...
NMR Relaxation And Charge Transport In Conducting Polymers
(2010-10-14)
Conducting and semiconducting polymers, consisting of delocalized π-electrons, have been studied for the past three decades. These materials have shown novel physical properties with interesting applications in batteries, ...
Investigations Of Spin-Dynamics And Steady-States Under Coherent And Relaxation Processes In Nuclear Magnetic Resonance Spectroscopy
(Indian Institute of Science, 2007-03-07)
The existence of bulk magnetism in matter can be attributed to the magnetic properties of the sub-atomic particles that constitute the former. The fact that the origin of these microscopic magnetic moments cannot be related ...
On The Magnetic And Magnetotransport Studies Of Cobaltates And Superconductor/ Ferromagnet Heterostructures
(2011-06-30)
The study of the co-existence of singlet superconductivity and ferromagnetism in bulk materials has been a long standing and intriguing problem in condensed matter physics since the superconductivity and ferromagnetism are ...
Probing Anisotropic Interactions In Solid State NMR : Techniques And Applications
(2011-06-30)
The thesis aims at methodological developments in Nuclear Magnetic Resonance (NMR) and study of oriented samples like liquid crystals and single crystals and powder samples. Though methodological development in solid state ...
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. ...
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 ...
