Amanda Karen Petford-Long FREng is a Professor of Materials Science and Distinguished Fellow at the Argonne National Laboratory. She is also a Professor of Materials Science at Northwestern University.

Petford-Long studied physics at University College London, graduating in 1981. ^[3] She earned a Doctor of Philosophy degree from the University of Oxford in 1985 for research on Beta-alumina solid electrolytes supervised by Colin Humphreys. ^{[2] [3]} She was a postgraduate student at St. Cross College, Oxford. ^[2]

Petford-Long served as professor at Corpus Christi College, Oxford, from 2002. ^{[4] [5]} She worked on spray coated nanocomposite materials and magnetic nanoparticles and used an atom probe. ^{[6] [7] [8]} She was the only woman to be elected a Fellow of the Royal Academy of Engineering (FREng) in 2005. ^{[9] [10]} Petford-Long moved to Argonne National Laboratory in 2005. ^[3]

She served as director of the Center for Nanoscale Materials from 2010 to 2014, developing new techniques for nanoscale characterisation. ^[3] She delivered a lecture for the Chicago Council on Science and Technology in 2014. ^{[11] [12]}

She has explored the microstructure and magnetic field properties in multiferroic tunnel junctions. ^[13] She works with Jacqueline Johnson on fluorozirconate glass for novel ceramics, using pulsed laser deposition to fabricate thin films. ^{[14] [15]} She has demonstrated that nanoparticle crystallisation impacts the optical properties of the glass ceramics. ^[16] Pulsed laser deposition allows her to control the distribution of europium dopants and the nanocrystalline phase behaviour. ^[15] The applications include up and down-converters for solar cells. ^[15] She discussed their work on NPR in 2018. ^[17]

Petford-Long develops in situ magnetised transmission electron microscopy (TEM) methods for examining magnetic thin film structures. ^[18] She uses Lorentz transmission electron microscopy to identify the micromagnetic behaviour. ^[19] She created skyrmions, chiral spin structures with no net charge. ^{[20] [21]} They used an ion-beam, allowing them to make skyrmion-like structures at a variety of length scales. ^[22] She showed that non-repeating patterns in quasicrystals could be used to store information. ^[23]

She serves as chair of the American Physical Society Division of Materials Physics from 2018 to 2019. ^[24] She serves on the scientific advisory board of the Centre for Research on Adaptive Nanostructures and Nanodevices at Trinity College Dublin. ^[25] She is Chair of the Argonne National Laboratory Chief Research Officer Council. ^[3] She is an advocate for women in engineering and has been involved in initiatives to inspire young girls to choose engineering at college. ^{[26] [27] [28]}
