Whereas in Gd4Co3, S(T) is always negative, for x\u2009&amp;gt;\u20090 the substitution of Co for Cu gives rise to the appearance of a low temperature positive maximum in S(T) at around 30 K. Based on our previous study of these compounds, we argue that this maximum in S(T) originates from electron-magnon scattering and is sensitive to electron band structure changes resulting from the substitution of Co for Cu and the accompanying reduction in the ratio between the electron-magnon and the electron-phonon scattering strengths. The decreasing role of Co 3d electrons with the progressive substitution of Co for Cu, evidenced by a strong reduction in the spin disorder resistivity and the Co magnetic moment, is seen to be crucial for the existence of such a low temperature maximum in S(T) for x\u2009&amp;gt; 0.<\/jats:p>","DOI":"10.1063\/1.3549597","type":"journal-article","created":{"date-parts":[[2011,3,24]],"date-time":"2011-03-24T18:14:38Z","timestamp":1300990478000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Thermoelectric power of Gd4(Co1-<i>x<\/i>Cu<i>x<\/i>)3 compounds"],"prefix":"10.1063","volume":"109","author":[{"given":"T.
