Results are analyzed using equations derived analytically from the implicit equations of the Landau-Ginzburg-Devonshire (LGD) theory. Corrections due to cluster contribution attributed to the reorientation of random-field-induced polar nanometer-scale regions turn out to be important, if not decisive, for a reliable description of \u03b5\u2032(E). So, it is found that a combined equation including the Langevin-type cluster term, i.e., \u03b5L\u2032(E)=P02L3\u2215(2kBT\u03b50[cosh(P0L3E\u22152kBT)]2) is the most suited to describe the dc electric-field dependence of the dielectric constant around Tmax. Based on the fitting of the \u03b5\u2032(E) data, the cluster polarization P0 reaches values as high as \u223c0.4\u2009\u03bcC\u2215cm2 with the cluster size L of 11\u00b14.5\u2009nm. Thus, the existence in the Sr1\u2212xMnxTiO3 system of polar clusters with nanometer-scale size is consistent with \u03b5\u2032(E) data and their contribution to the permittivity at E=0 and temperatures close to Tm is estimated to be up to 30%. In addition, besides inducing the peak in \u03b5(T), the formation of polar nanoregions is beneficial to the high relative electric-field tunability of the dielectric constant nr=[\u03b5\u2032(0)\u2212\u03b5\u2032(E)]\u2215\u03b5\u2032(0)\u223c70% as well as high communication quality factor K=[\u03b5\u2032(0)\u2215\u03b5\u2032(E)\u22121]2\u2215[\u03b5\u2032(0)\u2215\u03b5\u2032(E)tan\u2009\u03b4(0)tan\u2009\u03b4(E)]\u223c10\u2009000 under 20\u2009kV\u2215cm at 10\u2009kHz.<\/jats:p>","DOI":"10.1063\/1.2717874","type":"journal-article","created":{"date-parts":[[2007,4,26]],"date-time":"2007-04-26T13:45:37Z","timestamp":1177595137000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":30,"title":["Nonlinear dc electric-field dependence of the dielectric permittivity and cluster polarization of Sr1\u2212xMnxTiO3 ceramics"],"prefix":"10.1063","volume":"101","author":[{"given":"Alexander","family":"Tkach","sequence":"first","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , Portugal"}]},{"given":"Paula M.","family":"Vilarinho","sequence":"additional","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , Portugal"}]},{"given":"Andrei L.","family":"Kholkin","sequence":"additional","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , Portugal"}]}],"member":"317","published-online":{"date-parts":[[2007,4,25]]},"reference":[{"key":"2023080102211477900_c1","doi-asserted-by":"publisher","first-page":"5","DOI":"10.1023\/B:JECR.0000015661.81386.e6","volume":"11","year":"2003","journal-title":"J.
