Secondary phases observed in pristine BiFeO<jats:sub>3<\/jats:sub> (BFO) ceramic were significantly suppressed in the co-substituted samples. Grain size decreased in the co-substituted samples. Raman study revealed ten active phonon modes which remained almost invariant with co-substitution. Out-of-plane piezoresponse (OPP-PFM) exhibited negative self-polarization effect in the virgin state (without any poling) which has been explained in terms of built-in electric field. The self-polarization effect is largest in 3% Sc co-substituted sample. Poling with \u00b130\u00a0V dc voltage demonstrated both positive and negative domains. Maximum difference in the peak values (from histograms) of such opposite domains was observed in the Bi<jats:sub>0.9<\/jats:sub>Pr<jats:sub>0.1<\/jats:sub>Fe<jats:sub>0.99<\/jats:sub>Sc<jats:sub>0.01<\/jats:sub>O<jats:sub>3<\/jats:sub> sample. Information from local measurements (such as PFM) should be useful in deciding such multiferroic materials for device application.<\/jats:p>","DOI":"10.1088\/0022-3727\/45\/5\/055302","type":"journal-article","created":{"date-parts":[[2012,1,20]],"date-time":"2012-01-20T12:37:52Z","timestamp":1327063072000},"page":"055302","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":75,"title":["Structural, morphological and piezoresponse studies of Pr and Sc co-substituted BiFeO<sub>3<\/sub> ceramics"],"prefix":"10.1088","volume":"45","author":[{"given":"Indrani","family":"Coondoo","sequence":"first","affiliation":[]},{"given":"Neeraj","family":"Panwar","sequence":"additional","affiliation":[]},{"given":"I","family":"Bdikin","sequence":"additional","affiliation":[]},{"given":"V S","family":"Puli","sequence":"additional","affiliation":[]},{"given":"R S","family":"Katiyar","sequence":"additional","affiliation":[]},{"given":"A L","family":"Kholkin","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2012,1,20]]},"reference":[{"key":"jphysd405441bib01","doi-asserted-by":"publisher","first-page":"759","DOI":"10.1038\/nature05023","volume":"442","author":"Eerenstein","year":"2006","journal-title":"Nature"},{"key":"jphysd405441bib02","doi-asserted-by":"publisher","first-page":"425","DOI":"10.1038\/nmat2189","volume":"7","author":"Bibes","year":"2008","journal-title":"Nature.
