Investigations in nuclear magnetic resonance.
Itoh and Kamiya?^ in their work on K?Cu?Cl?·2H?O have estimated that some of the unpaired electron spin density may lie on the protons of the water molecules. In the recent ENDOR study by van Ormondt et?al.?^ already ... -
Investigations in nuclear magnetic resonance.
From a study of ?Li NMR in single crystals of lithium acetate dihydrate, e²qQ/h and location of the EFG tensor are determined. e²qQ/h = 154.6 kHz, which, being on the higher side of the values obtained for other Li compounds, ... -
Investigations in X-ray crystallography
he crystal structure of glycine silver(I) nitrate has been solved in the non-ferroelectric phase by the heavy atom technique and refined to an R value of about 11% with four sets of intensity data, three sets collected at ... -
Investigations of AC response in certain type II superconductors
We have intentionally varied the microstructures of polycrystalline YBCO samples and studied their AC loss behavior. A close correlation between AC losses and the microstructures of the superconducting samples is observed. ... -
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 ... -
Investigations of Phase Change Memory Properties of Selenium Doped GeTe and Ge2Sb2Te5
(2018-04-05)GeTe and Ge2Sb2Te5 alloys are potential candidates for non-volatile phase change random access memories (PCRAM). For electrical data storage applications the materials should have stable amorphous and crystalline phases, ... -
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 ... -
Investigations On Certain Tellurium Based Bulk Chalcogenide Glasses And Amorphous Chalcogenide Films Having Phase Change Memory (PCM) Applications
(2014-09-04)Chalcogenide glass based Phase Change Memories (PCMs) are being considered recently as promising alternatives to conventional non-volatile Random Access Memories (NVRAMs). PCMs offer high performance & low power consumption, ... -
Investigations on deep-level defects in HgTe nanocrystals-based photovoltaic devices using a novel instrumentation for Deep Level Transient Spectroscopy
Colloidally produced nanocrystals (NCs) arranged in thin films hold promise for next-generation semiconductors. These NCs offer tunability in semiconductor properties due to their size, shape, composition, and surface ... -
Investigations On Electrodes And Electrolyte Layers For Thin Film Battery
(2013-07-03)The magnificent development of on-board solutions for electronics has resulted in the race towards scaling down of autonomous micro-power sources. In order to maintain the reliability of miniaturized devices and to reduce ... -
