Multifunctional oxide heterostructures exhibiting magnetoelectric properties show great potential in advanced applications which are attracting a number of recent investigations. Herein, hybrid structures are presented including the antiferroelectricity film PbZrO3 (PZO) and the ferrimagnetic insulator (FMI) yttrium iron garnet (Y3Fe5O12, (YIG)) film by means of pulse laser deposition and magnetron sputtering, respectively. A visible double ferroelectricity hysteresis loop for PZO at low electrical field and the distinct X-ray magnetic circular dichroism (XMCD) spectra for YIG are obtained. To study the spin current transfer processes between platinum (Pt) and the PZO/YIG system, the Pt film is deposited on the PZO/YIG bilayers as the conversion detector and the spin–charge conversion voltage can be obtained via inverse spin Hall effect (ISHE) under thermal gradient excitation. These results indicate that the hybrid structure PZO/YIG/Pt provides a potential route to realize an electric field control of spin–charge conversion and is instructive for future low-power multiferroic heterostructures-based spintronic devices.

混合结构 PbZrO3/Y3Fe5O12/Pt 中的自旋电荷转换
具有磁电特性的多功能氧化物异质结构在先进应用中显示出巨大的潜力，吸引了许多最近的研究。本文提出了混合结构，包括反铁电薄膜 PbZrO 3 (PZO) 和亚铁磁绝缘体 (FMI) 钇铁石榴石 (Y 3 Fe 5 O 12，（YIG））薄膜分别采用脉冲激光沉积和磁控溅射的方法。获得了低电场下 PZO 的可见双铁电磁滞回线和 YIG 的独特 X 射线磁圆二色性 (XMCD) 光谱。为了研究铂（Pt）和PZO/YIG系统之间的自旋电流转移过程，将Pt薄膜沉积在PZO/YIG双层上作为转换探测器，并通过逆自旋霍尔效应获得自旋电荷转换电压（ ISHE）在热梯度激发下。这些结果表明，混合结构PZO/YIG/Pt为实现自旋电荷转换的电场控制提供了潜在的途径，并对未来基于低功耗多铁异质结构的自旋电子器件具有指导意义。
