چکیده
In this paper we compare the magnetic and electron paramagnetic resonance (EPR) properties of Pr0.5Ca0.5MnO3 (PCMO) Bi0.5Ca0.5MnO3 (BCMO) charge ordered manganites. PCMO BCMO samples were prepared by solid state reaction method. A commercial SQUID magnetometer was used to study dc-magnetization in temperature range 10-300 K. The EPR experiments carried out using a X-band (frequency ? 9.4 GHz) spectrometer 4 K – 300 Marked differences are found when rare earth bismuth based manganites compared. dependent fields seen be opposite each other. shows field behavior similar other manganites, i.e., decreases with decrease whereas increases temperature. could due different structures present manganite.

To investigation non-bonded interaction of the [CuF4]2- complex inside nanoring, we focus on the single wall boron-nitride B18N18 nanoring. Thus, the geometry of B18N18 nanoring has been optimized by B3LYP method with EPR-II basis set and geometry of the [CuF4]2- complex has been optimized at B3LYP method with Def2-TZVP basis set and Stuttgart RSC 1997 Effective Core Potential.

متن کاملelectron-paramagnetic-resonance studies using oxygen-17
Studies of the effect of substitution with 170 on the e.p.r. spectra at 9 and 35 GHz of Mo(V) in the phosphate complex of sulphite oxidase are reported. Substitution of '7O-enriched water for normal water, for samples of the enzymes reduced by sulphite in the presence of normal phosphate, produced no detectable effect on the e.p.r. signal. If phosphate substituted with 170 was used, coupling du...
متن کاملMagnetic Raman optical activity and Raman electron paramagnetic resonance
All molecules in a magnetic field parallel to the incident light beam show a small difference in the intensity of Raman scattering at 900 in right and left circularly polarized incident light. The most interesting effects occur in vibrational resonance Raman scattering from odd—electron transition metal halides, and in pure electronic resonance Raman scattering from both odd— and even—electron ...
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 ...
