Physicists Finally Observe a 50-Year-Old Theory Come to Life in a 2D Crystal

By cooling an atom-thin magnetic material, physicists have experimentally confirmed a classic 1970s model of two-dimensional magnetism. Bizarre things happen when materials are thinned from bulk crystals down to layers just one atom thick. In a study published in Nature Materials, physicists at The University of Texas at Austin reported that they have observed a [...]
