The world economy is becoming ever more reliant on high tech electronics such as computers featuring fingernail-sized microprocessors crammed with billions of transistors. For progress to continue, for Moore’s Law — according to which the number of computer components crammed onto microchips doubles every two years, even as the size and cost of components halves — to continue, new materials and new phenomena need to be discovered. Researchers have now discovered a “kaleidoscope” of phases, which represent the lowest-energy states that are allowed given the magnetic interactions.
