Current density imaging by pulsed conduction electron spin resonance
2007-01, Drescher, Malte, Kaplan, Noam, Dormann, Elmar
In analogy with Nuclear MRI, the ESR signal phase shift of conduction electrons moving in electrical currents along controlled magnetic field gradients can be used to generate spatial electronic current density maps. First two-dimensional images of the current density distribution in quasi-one-dimensional organic conductors are presented.
Pyrolytic carbon layers : an electron spin resonance analysis
2003, Drescher, Malte, Hüttinger, Klaus J., Dormann, Elmar
Chemical vapour infiltration is simulated by deposition of pyrolytic carbon on planar boron nitride substrates and carbon fibers in a hot-wall tubular reactor at about 1100 °C for varied pressure and flow-velocity of methane. The degree of orientation of the deposited graphite-like domains can be monitored via orientation and temperature dependence of the electron spin resonance parameters (g-tensor, linewidth). The electronic structure of the localized defects and conduction electrons is accessible by a quantitative modelling of these parameters. The interaction of the built-in hydrogen atoms with the unpaired electron spins is analysed by electron–proton spin double resonance technique (Overhauser shift)
