To check for ferrimagnetic resonances that are self-biased through a combination of Heisenberg exchange, crystalline anisotropy and crystallite size, we used the Agilent [dagger] slim probe and report the relative magnitude of reflected wave ([S.
This figure shows low concentrations of ferrimagnetic minerals in the presence of high IRMh% values and high concentrations of total free iron (Fe CDB).
The fact that there are no VM particles in size 4 (250-500 [micro]m) suggests that the processes causing formation of ferrimagnetic material are biased toward larger particle sizes.
If it is assumed that significant proportions of ferrimagnetic material in the surface soils in this study resulted from fire enhancement, what accounts for our findings that the reverse is true?
As aggregates disintegrate through time, the smaller particles from within the aggregates would carry less of the ferrimagnetic material than the aggregate coating.
Figure 13 shows low concentrations of ferrimagnetic minerals in the presence of high IRMh% values and high concentrations of total free iron (Fe CDB); and there is a very noticeable presence of paramagnetic material.
It is possible therefore that the high level of Al in the P layer is responsible for the small amount of ferrimagnetic material and the larger amounts of paramagnetic and canted anti-ferromagnetic material.
Fine P, Singer MJ, Laven R, Verosub K, Tenpass J (1993) New evidence for the origin of ferrimagnetic minerals in Loess from China.
The primary Alaskan loess, then, comprises a high concentration of MD ferrimagnetic grains, and relatively few fine SP ferrimagnetic grains, whereas the primary Chinese loess has a lower overall concentration of magnetic minerals and a greater mixture of SE SD, and MD phases.
This gradual and regular change of magnetic parameters from loess to soils in the Loess Plateau reflects a simple aeolian and pedogenic system (under moisture and temperature conditions suitable for ferrimagnetic minerals).
In detail the AK3 heating curve shows an initial increase in X compatible with the unblocking of a ferrimagnetic phase, with a maximum unblocking temperature of ~250 [degrees] C followed by the first drop of [Chi] between 250 [degrees] C and 450 [degrees] C.
This major increase in [Chi] supports the interpretation of the peak in the heating curve at ~410 [degrees] C as due to the production of a more magnetic phase (magnetite) from weakly ferrimagnetic or paramagnetic iron sulfides (Roberts et al.
fd] is an indicator of ultra-fine grained superparamagnetic ferrimagnetic minerals (Maher 1986).
Rainfall in the Loess Plateau significantly influences pedogenesis there through the in situ formation of fine-grained ferrimagnetic minerals.
fd] is used to indicate the presence of ultra-fine ferrimagnetic magnetite and/or maghaemite formed during pedogenesis (Heller et al.
