“…Similar phenomena were observed in manganites doped with rare-earth elements which contains two crystallographic (P21/m and Pnma) and two antiferromagnetic phases [9][10][11]. The proportion between the phases can be varied by magnetic field; e.g., the neutron diffraction experiment on Ca 0.85 Sr 0.15 MnO 3 [12] show the increase in the orthorhombic phase volume to 56 % in magnetic field 60 kOe at T = 100 K due to the decrease in the monoclinic phase volume from 94 to 44 %.…”

The Bi2(Sn0.95Mn0.05)2O7 compound existing simultaneously in two polymorphic modifications, namely, orthorhombic and cubic has been synthesized for the first time by solid-phase synthesis. The magnetic, dielectric and electrical properties of the compound have been studied. Anomalies in the temperature dependences of the electrical resistance and magnetic propoties have been found. These features are explained as martensitic phase transitions.

“…One possible solution would be the exploration of the large shape memory effect (SME) /mechanical strain in an oxide material in order to enable integration with microelectronics. Microstructural analysis and theoretical studies predict that a martensitic behavior may exist in functional oxides such as manganites [17][18][19] and piezoelectrics [20]. Piezoelectric oxides can usually exhibit a maximum electric field induced strain of ~1.7% [21,22] with a large susceptibility [23][24] and frequency bandwidth of their mechanical response [25][26][27].…”

Stimulus-responsive shape-memory materials have attracted tremendous research interests recently, with much effort focused on improving their mechanical actuation. Driven by the needs of nanoelectromechanical devices, materials with large mechanical strain, particularly at nanoscale level, are therefore desired. Here we report on the discovery of a large shapememory effect in bismuth ferrite at the nanoscale. A maximum strain of up to B14% and a large volumetric work density of B600 ± 90 J cm À 3 can be achieved in association with a martensitic-like phase transformation. With a single step, control of the phase transformation by thermal activation or electric field has been reversibly achieved without the assistance of external recovery stress. Although aspects such as hysteresis, microcracking and so on have to be taken into consideration for real devices, the large shape-memory effect in this oxide surpasses most alloys and, therefore, demonstrates itself as an extraordinary material for potential use in state-of-art nanosystems.
