Alternating commensurate - incommensurate structures in the magnetic
The magnetic phase diagram of the quasi one-dimensional spinchain system CsNiF 3 below the Néel temperature is determined. For magnetic fields perpendicular to the spin chains incommensurate phases are predicted. From linear spin-wave theory we obtain the instability line of the paramagnetic phase as a function of the strength and the direction of the field. The system undergoes a transition to...
متن کاملتوصیف ترمودینامیکی سیستم Ti-O براساس انتخاب مدل مایع یونی برای فاز مایع
In this study, the phase diagram and thermodynamic properties of Ti-O system up to 30 mole percent of oxygen was calculated with Calphad method. In this range of oxygen, Ti-O system includes αTi, βTi and liquid phases. αTi and βTi were modeled by “sublattice” model and the model of liquid phase was modeled by “ionic liquid”. Gibbs energy parameters ...
متن کاملSTRUCTURAL AND MAGNETIC PROPERTIES OF Co-Nd SUBSTITUTED ZnFe2O4 FERRITES SYNTHESIZED BY CO-PRECIPITATION TECHNIQUE
A series of Zn1-xCoxNdyFe2-yO4 spinel ferrites (x=0,0-0.5, y=0.00-0.10) was synthesized using the co-precipitation method sintered at 1000 o C. Synthesized Ferrites were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometery (VSM). The diffraction patterns show the formation of the spinel phase along with some traces of second phase Nd2O3...
متن کاملPhase diagrams in the Blume-Emery-Griffiths Ising thin films
We study the spin-1 Ising model with bilinear and biquadratic exchange interactions and single-ion crystal field. In addition to the four usual phases: disordered DIS, ferromagnetic FER, antiquadrupolar AQU and ferrimagnetic FRI, we found three new phases in the case of a thin magnetic film, namely: the sublattice A non magnetic phase NMA, the sublattice B non magnetic phase NMB and the global ...
متن کاملFormulation Design and Development of Self-Nanoemulsifying Drug Delivery Systems Containing a Hydrophobic Selective β1-Adrenoreceptor Blocker
The present work was aimed to design and develop self-nanoemulsifying drug delivery systems (SNEDDS) with the objective to overcome the problems associated with the delivery of talinolol, a hydrophobic and poorly bioavailable drugs having pH dependant solubility. The solubility of talinolol in various oils, surfactants, cosurfactants and aqueous phases were determined to identify and select the...
