An electron paramagnetic resonance study of Pr0.6Ca0.4MnO3 across the charge ordering transition
We report the first electron paramagnetic resonance studies of single crystals and powders of Pr0.6Ca0.4MnO3 in the 300-4.2 K range, covering the charge ordering transition at ∼ 240 K and antiferromagnetic transition (TN ) at ∼ 170 K. The asymmetry parameter for the Dysonian single crystal spectra shows anomalous increase at Tco. Below Tco the g-value increases continuously, suggesting a gradua...
متن کاملMAGNETISATION 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 کاملMnO 3 near the charge - ordering transition
We have studied low frequency resistance fluctuations (noise) in a single crystal of the rare earth perovskite manganite Pr0.63Ca0.37MnO3 which shows a charge ordering transition at a temperature TCO ≈ 245K. The measurements were made across the CO transition covering the temperature range 200K < T < 330K and frequency range 10Hz < f < 10Hz. The noise measurements were made using an ac bias wit...
متن کاملEnhanced Spin Susceptibility toward the Charge-Ordering Transition in a Two-Dimensional Extended Hubbard Model
Based on the non-skeleton diagrammatic expansion satisfying the compressibility and spinsusceptibility sum rules, we investigate static charge and spin responses in a two-dimensional extended Hubbard model with the nearest-neighbor Coulomb repulsion in the vicinity of its charge-ordering transition point. In this expansion, we can calculate approximate charge and spin response functions by syst...
متن کاملElectron Spin Resonance
The vast majority of magnetic resonance imaging and spectroscopic investigations make use of nuclear magnetic resonance (NMR), exploiting the interactions of atomic nuclei with applied static and radiofrequency magnetic fields. Nevertheless, there exists another important “flavour” of magnetic resonance, called Electron Spin Resonance (ESR) – or, interchangeably, Electron Paramagnetic Resonance...
