Abstract

In this work, electrical permittivity, magnetic and anelastic measurements in lead iron niobate ceramics (PFN) were performed in the frequency and temperature range from 1 kHz to 10 MHz and from 15 K to 400 K, respectively. Anelastic results characterized unambiguously the magnetoelectric effect in the PFN, demonstrating that ME coupling arises indirectly via strain contribution rather than a direct coupling between electrical and magnetic order parameters.Univ Fed Sao Carlos, Dpto Fis, GCFerr, BR-13565670 Sao Carlos, SP, BrazilUniversidade Federal de São Paulo, Dept Ciencia & Tecnol, BR-12231280 Sao Jose Dos Campos, SP, BrazilUniv Estadual Campinas, LPCM, DFA, IFGW, Campinas, SP, BrazilUniversidade Federal de São Paulo, Dept Ciencia & Tecn...
