Room-temperature multiferroic liquids: ferroelectric and ferromagnetic order in a hybrid nanoparticle–liquid crystal systemNádasi, Hajnalka (Avtor) Medle Rupnik, Peter (Avtor) Lisjak, Darja (Avtor) Sebastián Ugarteche, Nerea (Avtor) Mertelj, Alenka (Avtor) Eremin, Alexey (Avtor) liquid crystalsmultiferroicsferroelectric materialsferromagnetic materialsResponsiveness to multiple stimuli and adaptivity are paramount for designing smart multifunctional materials. In soft, partially ordered systems, these features can often be achieved via self-assembly, allowing for the combination of diverse components in a complex nanostructured material. Here, an example of a liquid is demonstrated that simultaneously displays both ferroelectric and ferromagnetic types of order. This material is a nanostructured liquid crystalline hybrid comprising ferrimagnetic barium hexaferrite nanoplatelets suspended in a ferroelectric nematic host. Director-mediated interactions drive the self-assembly of nanoplatelets in an intricate network. Due to the coupling between the polar electric and magnetic types of order, this material demonstrates magnetically driven electric and nonlinear optical responses, as well as electrically driven magnetic response. Such multiferroic liquids are highly promising for applications in energy harvesting, nonlinear optics, and sensors.Wiley20252025-08-19 11:55:21Neznano23331UDK: 54ISSN pri članku: 1521-4095DOI: 10.1002/adma.202508406COBISS_ID: 244049923ZDAsl© 2025 The Author(s).
