چکیده

We present new results obtained from ESR experiments in the paramagnetic and magnetic ordered states of both crystallographic phases of the magnetic semiconductor GaCr4S8. We observe a critical behaviour typical of magnetic phase transitions, resulting in a shift and a broadening of the resonance line as well as a distortion of its shape. These features are discussed and related to the presence of magnetization fluctuations. J. Physique LETTRES 44 (1983) L-393 L-401 15 m 1983, Classification Physics Abstracts .

Application of Magnetic Nano Adsorbent Fe2O3 for Removal of Hazardous Ponceau-S Dye from Aqueous Solution

The photodegradation of Ponceau-S dye was investigated using UV radiation in presence of nanosized Fe2 O3 .Removal efficiency of Ponceau-S was sensitive to the operational parameters such as dye concentration, catalyst dose, pH, contact time, TOC and COD. The photocatalytic treatment of red colored Ponceau-S dye by magnetic nano semiconductor (Fe2 O3 )is an effective, economic and faster mode. ...

بررسی آشوب اتلافی در ابرشبکه‌های نیمرسانا

In this paper the motion of electron in a miniband of a semiconductor superlattice (SSL) under the influence of external electric and magnetic fields is investigated. The electric field is applied in a direction perpendicular to the layers of the semiconductor superlattice, and the magnetic field is applied in different direction Numerical calculations show conditions led to the possibility of ...

Room Temperature Ferromagnetism in Cobalt Doped ZnO Nanoparticles

In this work we report synthesis and magnetic characterization of cobalt doped ZnO nanoparticles (with different percent of doped cobalt oxide). Synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and N,N-methylene bisacrylamide as a lattice reagent. Characterization of the ...
