2. Translation: A minor discovery blown up by big words.

A system that behaves like bar-magnets? Amazing!
No, wait. Mn/Fe(100) behaves the same and works at room temperature.

A Curie-temperature of 0.4K? Amazing!
No, wait. You can reach 1K by a He3-cryostat, 4K by a He4-cryostat, 77K by a nitrogen-cryostat and 293K is room-temperature. The effort to get down to 0.4K removes this experiment light-years from any practical applications.

They can achieve the loss of this order by turning on an electromagnetic field? Amazing!
No, wait. If your magnetic field gets strong enough (I assume some milli-Tesla in this case), it will at some point dominate the Spin-Spin-interaction and force the Spins into a new direction.

Not all that minor. daaron Jun 2012 #3

Skepticism and excitement are both legitimate responses caraher Jun 2012 #5

Excellent - I was hoping to provoke a thoughtful response --> daaron Jun 2012 #6

ok daaron Jun 2012 #10

It all boils down to one question: "So what?" DetlefK Jun 2012 #12

See for me it comes down to "That's nice." daaron Jun 2012 #13

Actually, quaternions can be handy in "real life" caraher Jun 2012 #14

Yep. Quaternions do have some applications --> daaron Jun 2012 #15

"The domain of mad scientists?" Oy, spare me. (nt) Posteritatis Jun 2012 #11
