Off the axis: A new lead-free bismuth based perovskite has been formed at ambient pressure in the polar Pmc21 structure. Measurements give evidence for ferroelectricity and piezoelectricity. The material is significant due to a rotation of the polarization direction off the [111]p axis, making it important to the design of materials with a morphotropic phase boundary.
