چکیده
Frozen samples of aqueous solutions of oxidized Pt 6-methyl-uracil "blue" were studied bv ESR spectroscopy at temperatures T ranging between —196 °C and —10 °C. When T was raised a distinct change in the line pattern was observed at about —35 °C. The resulting type of spectrum is very similar to the ESR spectrum of MAGNUS' Green Salt. The observed effect is suggested to be due to a change of the nature of the system's electronic states possibly indicating a structural rearrangement.

MAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

متن کاملESR study of the Prussian blue analogue Rb0.8Mn1.1[Fe(CN)6] D2O
We performed electron spin resonance (ESR) studies of the mixed valence Prussian blue analogue, Rb0.8Mn1.1[Fe(CN)6] D2O in a wide frequency (9.5–319GHz) and temperature (3.5–300K) interval. Evidence for the proposed high-temperature Mn (S 1⁄4 5 2 )–NC–Fe (S 1⁄4 1 2 ) to low-temperature Mn (S 1⁄4 2)–NC–Fe (S 1⁄4 0) internal charge transfer has been detected: a characteristic reduction of wESRT o...
متن کاملESR and Magnetization Studies of Bi-manganites
The electron spin resonance (ESR) and magnetization (M) studies of Bi-manganites were undertaken to understand the coexistence of various magnetic phases and their effect on charge ordering as a function of composition and temperature. The studies on several compositions of Bi-manganites reveal that the electronic phase separation (PS) is an in‐ trinsic phenomenon in this system.
متن کاملPossible unconventional superconductivity in substituted BaFe2As2 revealed by magnetic pair-breaking studies
The possible existence of a sign-changing gap symmetry in BaFe2As2-derived superconductors (SC) has been an exciting topic of research in the last few years. To further investigate this subject we combine Electron Spin Resonance (ESR) and pressure-dependent transport measurements to investigate magnetic pair-breaking effects on BaFe1.9M0.1As2 (M = Mn, Co, Cu, and Ni) single crystals. An ESR sig...
