What happens when you combine the uber-tenacity of star
physics students with new nano engineering tools? You find the key to a
century-old scientific challenge.
You might describe physics as a science discipline with a
very high barrier to entry; drawing on tools like advanced math, bleeding edge
computational modeling and emergent platforms like nano technology.
These highly complex considerations take the form of some
very challenging questions. Take for example, the Barkhausen effect. Barkhausen offered science a seminal
experiment in 1919 that provided the first evidence of magnetic domains – or
the quilt-like patterns in the orientation of "magnetization" within
magnetic materials. Barkhausen made the
discovery by listening in on magnetic activity by wrapping a magnet with an
electrical coil – connected to a speaker. The messages Barkhausen received were
intermittent and idiosyncratic and impossible to translate until now. After
almost 100 years of trying, a U of A science team has cracked the code.
