Issue Date: | 2009 | Source: | Applied physics letters, 2009, v. 94, no. 8, 82904, p. 082904-1-082904-3 | Abstract: | A profound interplay between ferroelastic strain, polarization, and external magnetic field was observed in both bilayer and trilayer laminate Tb0.27-0.30Dy0.73-0.70Fe1.90-1.95 (Terfenol-D)/Bi12GeO20. The bilayer shows a much higher shear strain induced magnetoelectric effect than the trilayer. A series of experimental results related to the ferroelasticity in Bi12GeO20 such as a butterfly loop of the surface strain of Bi12GeO20 to magnetic field and a reproducible magnetic-field-induced strain switching were observed for the bilayer laminate. | Keywords: | Bismuth compounds Dielectric polarisation Dysprosium alloys Ferroelasticity Ferroelectric switching Ferroelectric thin films Iron alloys Magnetic field effects Magnetic multilayers Magnetoelectric effects Multiferroics Terbium alloys |
