My short stay in #HongKong has been full of #nickelates (mainly La327), but also of nice food, people and art. Among the others, happy to have listened at Prof. Zhang’s talk, yes the one of the Zhang-Rice #Singlet #bonding #antibonding in a two-orbitals model for nickelates
🔦#SpotlightonScience Scientists have uncovered a previously unknown crystal structure in a layered nickelate material known for high-temperature superconductivity, using high-pressure X-ray diffraction at ESRF beamline ID27. Read more 👉esrf.fr/home/news/spot… @lightsources
In a collaborative effort, we have discovered a new crystal structure in La₃Ni₂O₇, a material known to exhibit high-temperature superconductivity under high pressure. Read more at: fkf.mpg.de/8383096/2024_1…

What happens to this nickel-based compound when it’s subjected to a pressure equivalent to the force that 120 elephants would exert on the area of a postage stamp? go.nature.com/3sWWKNc
🚨 Deadline approaching! 🚨 We're accepting applications for PhD students! This competitive doctoral program provides students with an excellent platform for a career in solid state chemistry, condensed matter physics, and materials science. imprs-cms.mpg.de
😍Very impressive work! This is the final nail in the coffin for #LK99 - no point wasting any more time trying to replicate the Korean paper at this point! "Pure crystals of LK-99, synthesized by a team at the Max Planck Institute for Solid State Research in Stuttgart, Germany"…
We've been working on advancing single-crystal synthesis of perovskite rare-earth nickelates, a quantum material known for its exceptional electronic and magnetic properties! Learn more about our work at: fkf.mpg.de/8092709/2023_0…
We're reopening our search for a dedicated PhD candidate. If you're passionate about exploring material properties with light, we'd love to hear from you. Details: euraxess.ec.europa.eu/jobs/129461. Please retweet! #multiferroics #ferroelectrics #RamanSpectroscopy #PhDposition
We investigate the doping dependence of low-energy plasmon excitations in the cuprate superconductor La2-xSrxCuO4 using #RIXS 👉🏼 journals.aps.org/prb/pdf/10.110… @PhysRevB @YESuyolcu @mpifkf @HZB_BESSY @advancedphoton
Read our recent paper on topotactically induced oxygen vacancy order in nickelate single crystals. @Yu_Mi_Wu @YESuyolcu @MatthiasHepting journals.aps.org/prmaterials/ab…
Happy to share our recent publication @PhysRevMater! Congratulations, @Yu_Mi_Wu, for the great work @mpifkf! Our observations underpin a pyramidal-type brownmillerite-like structure in the nickelates through a topotactic reduction. @MatthiasHepting journals.aps.org/prmaterials/ab…
We have an open PhD position at the IMMM, Le Mans University about “Raman and non-linear laser spectroscopy on multiferroic materials”. If you are curious to discover ferroic properties with light, you should apply OR spread the word. 🔬🧲
New paper in @PhysRevMater. We report the first synthesis of millimeter-sized crystals of nickelates with the infinite-layer structure 👉🏼 journals.aps.org/prmaterials/ab… @mpifkf @esrfsynchrotron
My group is looking for two PhD students starting 9/2023 to implement quantum sensing microscopies at milli-Kelvin temperatures and perform electrical transport measurements on our topological thin film materials. Please RT and help spread the word! Link: mp.weixin.qq.com/s/pxgq4X0A6s3R…
Fresh off the press: news & views article in @NatureMaterials about the recent discovery of charge order next to the superconducting phase in layered nickelates nature.com/articles/s4156…
