Co2FeGe thin films were obtained by DC magnetron sputtering and show the saturation magnetization at T\u2009=\u200910\u2009K of m\u22485.6\u03bcB\/f.u., close to the value predicted by the Slater-Pauling rule. First-principles calculations of the electronic structure and the dielectric tensor are performed using the full-potential linearized-augmented-plane-wave method in the generalized gradient approximation (GGA) and GGA\u2009+\u2009U approximation. The measured interband optical conductivity spectrum for the alloy exhibits a strong absorption band in the 1\u20134\u2009eV energy range with pronounced fine structure, which agrees well with the calculated half-metallic spectrum of the system, suggesting a near perfect spin-polarization in the material.<\/jats:p>","DOI":"10.1063\/1.4752870","type":"journal-article","created":{"date-parts":[[2012,9,21]],"date-time":"2012-09-21T13:48:38Z","timestamp":1348235318000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":33,"title":["Electronic structure, optical and magnetic properties of Co2FeGe Heusler alloy films"],"prefix":"10.1063","volume":"112","author":[{"given":"N.
