Ligand field effects in lanthanide ions compounds have consequences for optical and magnetic spectroscopy. In the analysis of electron paramagnetic resonance spectra of Gd3+ complexes, a major role is played by the zero field splitting (ZFS), which is a hi ...
Recently, several informative reports have been published on spectroscopy experiments performed on cleaved surfaces of the bilayered colossal magnetoresistive manganite La2-2xSr1+2xMn2O7 (Konoto et al 2004 Phys. Rev. Lett. 93 107201, Freeland et al 2005 Na ...
Within the past few years, the field of Electron Spin Resonance has become an important tool in physical, chemical and biological research. However, in many cases its usefulness is limited by the sensitivity of the experimental setup. A typical example is ...
The structure and the associated dynamics of a series of poly(?-benzyl-L-glutamate)-b-poly(dimethyl siloxane)-b-poly(?-benzyl-L-glutamate) (PBLG-b-PDMS-b-PBLG) triblock copolymers were investigated using small- and wide-angle X-ray scattering, NMR, transmi ...
We present a newly-developed microwave probe for performing sensitive high-field/multi-frequency electron spin resonance (ESR) measurements under high hydrostatic pressures. The system consists of a BeCu-made pressure-resistant vessel, which accommodates t ...
Electronic and magnetic properties of quasi-one dimensional ormore widely low-dimensional systems aswell as their related correlated electron phenomena have been at the very frontier of condensed matter physics for quite some time. The reduced dimensionali ...
We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complement ...
In this Letter we report the observation, by scanning tunneling microscopy, of a Mott metal to insulator transition at the surface of 1T-TaSe2. Our spectroscopic data compare considerably well with previous angle-resolved photoemission spectroscopy measure ...
The relaxor ferroelectric PbMg1/3Nb2/3O3 (PMN) is investigated by means of dielectric and Fourier transform far infrared transmission spectroscopy in ,the frequency range from 10 kHz to 15 THz at temperatures between 20 and 900 K using mostly thin films on ...
We propose a model to determine the influence of different cell properties, such as size, membrane capacitance and cytoplasm conductivity, on the impedance spectrum as measured in a microfabricated cytometer. A dielectric sphere of equivalent complex permi ...
