Nanostructure orientation in 3D with visible light by Tomographic Müller-Polarimetric Microscopy
We developed a new method, tomographic Müller-polarimetric microscopy (TMPM), that allows to retrieve at three-dimensional microscopic resolution the nanoscale structural information of the ultrastructure probed with polarized light in a non-destructive manner using a low cost and experimentally simple optical setup.
Antiferrodistortive and ferroeletric phase transitions in freestanding films of SrTiO3
Epitaxially grown thin films are commonly used to strain engineer electronic properties by the choice of a substrate, and therefore do not match bulk properties (leading to properties that deviate from the bulk material). Free standing ultrathin oxide films are expected to preserve the bulk-like properties due to the absence of substrate influence. However, we show that this expectation is not fulfilled with ultrathin free standing SrTiO3, as they get ferroelectric at 80K.

New Monochromators for SLS 2.0
The brand-new monochromators that have been built by XDS Oxford for the hard X-ray beamlines at SLS 2.0 have now arrived. They were unpacked beginning of the week, and are currently being tested in our new lab space at Park Innovaare. These advanced instruments will play a crucial role in enhancing the beamline performance, ensuring superior precision and efficiency in the upcoming experiments.
Elusive multiferroicity in RNiO3 perovskites
In our recent paper we examined YNiO3 and proved that the RNiO3 type material known for its metal-insulator transition is in fact a type II multiferroic. We provide direct evidence of an electric-field-driven switch of the noncolliear magnetic state finally confirming the proposed type II multiferroic nature of YNiO3.

Phonon promoted charge density wave in topological kagome metal ScV6Sn6
Charge density wave (CDW) orders in vanadium-based kagome metals have recently received tremendous attention, yet their origin remains a topic of debate. The discovery of ScV6Sn6, a bilayer kagome metal featuring an intriguing √3 × √3 × √3 CDW order, offers a novel platform to explore the underlying mechanism behind the unconventional CDW. Here we combine ...
Weyl spin-momentum locking in a chiral topological semimetal
Spin–orbit coupling in noncentrosymmetric crystals leads to spin–momentum locking – a directional relationship between an electron’s spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin–momentum locking has been studied for decades, while its counterpart, isotropic parallel Weyl spin–momentum locking has remained elusive in experiments. Theory predicts ...
