Description:
Efforts to find the magnetic monopole in real space have been made in cosmic rays and in particle accelerators, but there has not yet been any firm evidence for its existence because of its very heavy mass, approximately 10(16) giga-electron volts. We show that the magnetic monopole can appear in the crystal momentum space of solids in the accessible low-energy region (approximately 0.1 to 1 electron volts) in the context of the anomalous Hall effect. We report experimental results together with first-principles calculations on the ferromagnetic crystal SrRuO3 that provide evidence for the magnetic monopole in the crystal momentum space.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fang, Zhong -- Nagaosa, Naoto -- Takahashi, Kei S -- Asamitsu, Atsushi -- Mathieu, Roland -- Ogasawara, Takeshi -- Yamada, Hiroyuki -- Kawasaki, Masashi -- Tokura, Yoshinori -- Terakura, Kiyoyuki -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Spin Superstructure Project, Exploratory Research for Advanced Technology (ERATO), Japan Science and Technology Corporation, National Institute of Advanced Industrial Science and Technology, Tsukuba Central 4, Tsukuba 305-8562, Japan. z.fang@aist.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526076" target="_blank"〉PubMed〈/a〉
