{"product_id":"9784431556596","title":"Charge and Heat Transport Phenomena in Electronic and Spin Structures in B20-type Compounds","description":"\u003cp\u003eThis thesis presents systematic experimental research on chiral-lattice crystals referred to as B20-type germanium compounds, especially focusing on skyrmion spin textures and Dirac electrons. An emergent electromagnetic field observed in MnGe demonstrates a formation of three-dimensional skyrmion crystals. Detection of skyrmions in nanoscale Hall bar devices made of FeGe is realized by measuring the topological Hall effect, a transport property reflecting emergent fields produced by skyrmions. By measuring the electron-filling dependence of thermopower in CoGe, a pronounced thermoelectric property in this compound is revealed to stem from the asymmetric density of states appearing at certain levels of Fermi energy in the Dirac electron state.\u003c\/p\u003e\u003cp\u003eThe three main results named above will contribute to enriching a variety of novel electromagnetic responses of emergent gauge fields in solids, to realizing high-performance skyrmion-based magnetic memory, and to designing high-efficiency thermoelectric materials, respectively.\u003c\/p\u003e","brand":"Springer Japan","offers":[{"title":"Default Title","offer_id":47058232869104,"sku":"9784431556596","price":129.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9784431556596_p0.jpg?v=1763713526","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9784431556596","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
