Magnetic order can survive weak quantum fluctuations in a gapless 2D magnet
Phys.org reports that a Physical Review Letters study found magnetic order can persist in disordered magnets that lack an energy gap.
TLDR
Phys.org reports that a gapless 2D magnet can retain its order under weak quantum fluctuations when its random bonds favor alignment, even though small clusters can flip at almost no energy cost.
