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. | URI: | http://hdl.handle.net/10397/7973 | ISSN: | 0003-6951 | EISSN: | 1077-3118 | DOI: | 10.1063/1.3089571 |
