Major-league magnetostriction Magnetoelectric materials polarize in response to either electric or magnetic fields, making them attractive for data-storage applications. Long et al. discovered a ytterbium-based molecular magnetoelectric material with high magnetoelectric coupling (see the Perspective by Zhou and Han). An applied magnetic field strains the material, which changes its electrical properties. The required field is much lower than other magnetoelectric materials, and this work highlights the potential for using molecular materials in devices. Science, this issue p. 671; see also p. 627 An ytterbium-based molecular magnetoelectric material has strong interaction between magnetic and ferroelectric properties. Magnetoelectric (ME) materials combine magnetic and electric polarizabilities in the same phase, offering a basis for developing high-density data storage and spintronic or low-consumption devices owing to the possibility of triggering one property with the other. Such applications require strong interaction between the constitutive properties, a criterion that is rarely met in classical inorganic ME materials at room temperature. We provide evidence of a strong ME coupling in a paramagnetic ferroelectric lanthanide coordination complex with magnetostrictive phenomenon. The properties of this molecular material suggest that it may be competitive with inorganic magnetoelectrics.

大联盟磁致伸缩 磁电材料响应电场或磁场而极化,使其对数据存储应用具有吸引力。龙等人。发现了一种具有高磁电耦合的镱基分子磁电材料(参见 Zhou 和 Han 的观点)。施加的磁场会使材料变形,从而改变其电气特性。所需的磁场远低于其他磁电材料,这项工作凸显了在器件中使用分子材料的潜力。科学,这个问题 p。第671话 另见第 627 镱基分子磁电材料在磁性和铁电特性之间具有很强的相互作用。磁电 (ME) 材料在同一相中结合了磁极化和电极化,为开发高密度数据存储和自旋电子或低消耗设备提供基础,因为有可能触发另一种属性。这种应用需要本构特性之间的强相互作用,这是室温下经典无机 ME 材料很少满足的标准。我们提供了在具有磁致伸缩现象的顺磁性铁电镧系元素配位络合物中强 ME 耦合的证据。这种分子材料的特性表明它可能与无机磁电材料竞争。经典无机 ME 材料在室温下很少满足的标准。我们提供了在具有磁致伸缩现象的顺磁性铁电镧系元素配位络合物中强 ME 耦合的证据。这种分子材料的特性表明它可能与无机磁电材料竞争。经典无机 ME 材料在室温下很少满足的标准。我们提供了在具有磁致伸缩现象的顺磁性铁电镧系元素配位络合物中强 ME 耦合的证据。这种分子材料的特性表明它可能与无机磁电材料竞争。
