Large elasto-electric response of the charge-ordered perovskite SmBaMn₂O₆ under an anisotropic strain

The interplay among various order parameters in quantum materials frequently results in exotic ground states and may facilitate revolutionary functional control. In the A-site-ordered manganite double perovskite SmBaMn2O6, it was demonstrated that an anisotropic strain of less than 0.1% can modulate electrical transport by over 6% near the Neel temperature. It is hypothesized that this phenomenon is due to the high sensitivity of spin fluctuation near the antiferromagnetic ordering to lattice distortion, resulting in significant changes in transport properties. This study offers a compelling approach for investigating the interaction between the electric properties of SmBaMn2O6 and in situ anisotropic strain.
