In automotive engineering, there are several idealized energy transfer
cycles which involve four clearly segmented stages of engine operation. For
instance, the Otto cycle consists of:
1) Intake, Compression, Expansion, Exhaust which are further arranged
as
2) Two isentropic processes - adiabatic and reversible and
3) Two isochoric processes - constant volume
4) As an "idealized" cycle, this never happens completely in practice,
but it permits substantial gain in a ratchet-like way and substantial
understanding of the process.
5) There are many other idealized cycles for combustion, such as the
Stirling which is probably closer, as an analogy, to nanomagnetism
In nanomagnetism, there is a corresponding strong metaphor involving a
similar kind of 4 legged hysteresis curve, where we find
1) Antiferromagnetism, superparamagnetism, ferrimagnetism and
superferromagnetism working in a repeating cycle
2) The remainder of the analogy is under development but there are two
reversible processes involving field alignment, requiring two operative
classes of reactants - one mobile and one stationary
3) Nanomagnetism requires a ferromagnetic nucleus which is nominally
stationary. (yes, palladium and titanium alloy can be ferromagnetic)
4) Nanomagnetism requires a mobile medium, loaded or absorbed into the
ferromagnet which has variable magnetic properties.
5) Hydrogen and its isotopes appears to be the exclusive mobile medium,
which can oscillate between diamagnetic (as a molecule) and strongly
paramagnetic (as an absorbed atom)
6) Spin coupling provides the transfer of energy from the ferromagnetic
nucleus to the mobile nucleus in a method similar to induction.
7) Inverse square permits very strong effective fields for transfer of
spin energy from nickel-62, for instance.
8) Nanomagnetism seems to boosted by the presence of an oxide of the
ferromagnet - i.e. nickel with a small percentage of nickel oxide but the
oxide is not required.
This is an emerging hypothesis, the details of which are fluid, but... shall
we say... "attractive" :-)
