Researchers pushing the limits of magnets as a means to create faster electronics published their proof of concept findings today, April 10, in the journal Science. . . . The team exploring methods for creating machines that operate at trillions of cycles per second includes the University of California, Santa Cruz and Riverside, Ohio State University, Oakland University (Michigan) and New York University, among others.
Today's computers rely on ferromagnets (the same kind that stick to your refrigerator) to align the binary 1s and 0s that process and store information. Anti-ferromagnets are much more powerful, but their natural state, displaying no net measurable magnetization, makes it difficult to harness their power.
The laboratory of Enrique del Barco, Ph.D., . . are successfully overcoming that natural resistance using electrical currents passed through anti-ferromagnets on the nanoscale. The results are groundbreaking because they represent proof of concept showing that antiferromagnetic devices can operate on the terahertz level—or calculations completed in a trillionth of a second. Not only does that hold potential for everything from guidance systems to communications, but it brings devices closer to mimicking the way the brain operates.

Magnets, how do they work?
Pretty well!
I bet that we and the Norwegians are paying for most of this and doing most of the research but the Chinese will steal it all.
Research cooperation with China has to stop immediately.
“Magnets, how do they work?”
Einstein told the story of his receiving a compass from his father. He could not get over his fascination that some magical Force was able to get through the case to the needle.
As an adult he reflected back; something is strange only if we are not familiar with.
We grow up with many things that we cannot explain but because they are familiar they are not strange. (leading to his thoughts on gravity).
They are attractive.

Core (magnetic) memory, so, 1950’s ....
Ping to Magnet discovery.
Now maybe we can anti gravity propulsion. I’d slap on a belt and float above the bilabong fishing for salmon.
They can also be very repulsive.
Magnet research is not very attractive
I suggest that we just dig up the Founding Fathers, wrap their corpses in copper wire and surround them with magnets.
The amount of electricity they produce by their constant and rapid spinning in their graves will provide all the electricity that 21st century societies will ever need.
We're going back. Google "magnetic semiconductor".
magnets use flux
I must be getting old as I remember when 1 millisecond access to a ferite core was considered fast.
