单词 | antiferromagnetism |
例句 | By combining the effects of electron repulsion and quantum mechanics, Anderson explained how iron atoms become magnetic, and accounted for the interactions that result in antiferromagnetism. Philip W. Anderson (1923–2020) 2020-04-30T04:00:00Z With ferromagnetism understood as deriving from the alignment of the individual magnetic moments of atoms in a crystal, Dr. Anderson provided a quantum explanation for what had been the perplexing property of antiferromagnetism. Philip Anderson, Nobel-winning theoretical physicist, dies at 96 2020-04-01T04:00:00Z In contrast, Anderson expounded the concept of emergence, which stated that as any system grew larger, new phenomena—such as antiferromagnetism and superconductivity—could emerge that could not be predicted from the fundamental interactions. Philip Anderson, legendary theorist whose ideas shaped modern physics, dies 2020-03-30T04:00:00Z The concept of antiferromagnetism, in which spins align in alternating directions and the average magnetic moment is zero, was developed only in the 1930s. Magnetic and topological order united in a crystal 2019-12-17T05:00:00Z They also spin like tops, and at low temperatures neighboring electrons spin in opposite directions, creating an up-down-up-down pattern of magnetism called antiferromagnetism. A step closer to explaining high-temperature superconductivity? 2015-02-27T05:00:00Z The key feature of the antiferromagnetism in manganese bismuth telluride is that it can retain a modified version of time-reversal symmetry. Magnetic and topological order united in a crystal 2019-12-17T05:00:00Z Consider adding such antiferromagnetism to a topological insulator. Magnetic and topological order united in a crystal 2019-12-17T05:00:00Z |
