Critical magnetic fields Table

In Table 3, some data for a family of the most promising A-15 type materials are presented with their critical magnetic fields, and the derivative of critical field with respect to transition temperature (all about 2.5 in value). These data were reported by Hulm and...

The resulting overall energy balance for the plant at nominal load conditions is shown in Table 3. The primary combustor operates at 760 kPa (7.5 atm) pressure the equivalence ratio is 0.9 the heat loss is about 3.5%. The channel operates in the subsonic mode, in a peak magnetic field of 6 T. AH critical electrical and gas dynamic operating parameters of the channel are within prescribed constraints the magnetic field and electrical loading are tailored to limit the maximum axial electrical field to 2 kV/m, the transverse current density to 0.9 A/cm , and the Hall parameter to 4. The diffuser pressure recovery factor is 0.6.

Maybe the major achievement provided by the discovery of the fe rfim is the possibility to study the complete set of critical exponents on a ferroic system for the first time after their prediction [9,10]. Table 15.1 shows the results as compared with predictions from theory and simulations. Most remarkably, the order parameter exponent ft (Figure 15.10) clearly deviates from the prediction ft 0 and achieves a value which comes close to that observed recently on the standard rfim system, the dilute uniaxial antiferromagnet Fci ,Zn.,F2, x = 0.15, in an external magnetic field [50], Further, the most disputed value, namely the specific heat exponent a [48] (Figure 15.12) clearly describes the same logarithmic divergence as that found on Fci. Zn. I 2, a 0 [10], which still lacks theoretical confirmation. 

Table 8.12. Values of the critical field Bo (T) for EM donors and acceptors in some semiconductors. As a magnetic-field dependence of the effective masses is not considered and because of the spread in the published values of the VB parameter Yi, these values should be regarded as estimates. For the H atom, Bo is 2.35 x 10B T...
