PM-FM transition in a DE model

چکیده
We study paramagnetic ferromagnetic transition due to exchange interaction between classical localized magnetic moments and conduction electrons. By solving the Dynamical Mean Field Approximation equations we find explicit formula for the transition temperature Tc for arbitrary electron dispersion law, concentration and relation between exchange coupling and the electron band width. We present the results of calculations of the Tc for the semi-circular electron density of states.

Transition from premutation to full mutation in fragile X syndrome is likely to be prezygotic.
In the fragile X syndrome, the transition from unmethylated moderate expansions of the CGG repeat (premutations) to methylated large expansions (full mutations) occurs only through maternal transmission. The risk of such transition is highly correlated with the size of the maternal premutation (PM), being very low for small PM alleles (approximately 60 repeats), to 100% for alleles above 100 re...
متن کاملBody composition techniques and the four-compartment model in children.
The purpose of this study was to compare the accuracy, precision, and bias of fat mass (FM) as assessed by dual-energy X-ray absorptiometry (DXA), hydrostatic weighing (HW), air-displacement plethysmography (PM) using the BOD POD body composition system and total body water (TBW) against the four-compartment (4C) model in 25 children (11.4 +/- 1.4 yr). The regression between FM by the 4C model ...
متن کاملReentrant spin glass transition in La0.96−yNdyK0.04MnO3: origin and effects on the colossal magnetoresistivity
– Magnetic, electric and structural properties of La0.96−yNdyK0.04MnO3+δ with 0≤ y ≤0.4 have been studied experimentally. A disordered magnetic state is formed as La is substituted by Nd, reflecting the competition between ferromagnetic (FM) double exchange and antiferromagnetic superexchange interactions. Key structural parameters are identified and correlated with changes in magnetic and elec...
متن کاملModulation and Detection
H. J. De Los Santos et al., Radio Systems Engineering, DOI 10.1007/978-3-319-07326-2_2, © The Authors 2015 Abstract In this chapter, we present a number of topics surrounding modulation and demodulation. We begin by introducing system-level block diagrams of AM and FM/PM modulators and demodulators, and explaining their respective principles of operation. In particular, under the topic of AM Mo...
متن کاملHydrodynamics and water quality assessment of a coastal lagoon using environmental fluid dynamics code explorer modeling system
Ciénaga de Mallorquín is a coastal lagoon designated as a RAMSAR site due to its ecological regional and international importance. In this work, the environmental fluid dynamics code explorer modeling system was implemented to determine the spatio-temporal distribution of temperature, dissolved oxygen, chemical oxygen demand and nutrient levels, and assess the trophic status of Ciénaga de Mallo...
