Bismuth Ferrite (BFO) is a fascinating material in which magnetic order can be controlled purely through electrical means, making it a promising candidate for ultra-efficient, next-generation spintronic devices. The Qnami ProteusQ has been effectively utilized to image its electrical and magnetic domains, as demonstrated by numerous publications.
Paul Stevenson’s research at Northeastern University utilized the Qnami ProteusQ microscope to enhance vector magnetometry, allowing precise measurement of both parallel and perpendicular stray fields in complex materials like bismuth ferrite.
Vincent Garcia’s team, using ProteusQ, demonstrated electrically controlled topological states in BiFeO₃, advancing reconfigurable antiferromagnetic spintronics.
Ramamoorthy Ramesh’s team, using Scanning NV data from Proteus Q, demonstrated ferroelectric control of magnons in BiFeO₃, enabling energy-efficient spin transport for low-dissipation nanoelectronics.
Felix Casanova's team used Qnami products to demonstrate voltage-controlled magnetization switching and reading in nanodevices, paving the way for low-power magnetoelectric spin-orbit logic.
Scanning NV Magnetometry unlocks the characterization of the effects of strain and electrical fields on exotic antiferromagnetic spin textures in multiferroics.
French research group led by Prof. M. Viret uses scanning NV magnetometry to reveal a novel type of chiral spin-textures occurring on BiFeO3’s domain-walls.
