Frank, I am only familiar with the term in regard to magnetics - is there a big difference in meaning in materials science (over the basic notion of 'temporal continuity' ). It should be noted, for those who do not remember all of Feynman's pronouncements (and I have forgotten the correct terminology but it is not 'hysteresis') but relates to structural 'coherence' such as crystal structure - in itself is a physical 'ordering' property which can be used for possible power production, when disrupted (into disorder)... and with an energy-content in the range of a fractional eV per atom - perhaps double what you get from buring gasoline in air yet with no 'obvious' chemical redox reaction...
