The main areas of research at PSI
Recent highlights from our research
On the way to light-controlled medicine
PSI researchers have elucidated the structure of special photoreceptors.
How catalysts remove dangerous nitrogen oxides
In industrial catalysis, iron is not equal to iron.
Tumour irradiation, individualised daily
A PSI feasibility study shows: Even in everyday clinical practice, treatment can be adapted daily. Thus, the tumour will always be treated with exactly the right dose of radiation.

Reentrant multiple-q magnetic order and a “spin meta-cholesteric” phase in Sr3Fe2O7
Topologically nontrivial magnetic structures such as skyrmion lattices are well known in materials lacking lattice inversion symmetry, where antisymmetric exchange interactions are allowed. Only recently, topological multi-q magnetic textures that spontaneously break the chiral symmetry, for example, three-dimensional hedgehog lattices, were discovered in centrosymmetric compounds, where they are instead driven by frustrated interactions. Here we show that ...
Skyrmion topology quantified in 3D
Researchers from an international collaboration between the United States of America and Switzerland have performed three-dimensional magnetic imaging of a magnetic skyrmion using soft X-ray laminography. This allowed for the investigation, in three dimensions, of the topological profile of the magnetic skyrmions.
Dual-site reaction mechanism for the simultaneous reduction of nitrous and nitric oxides
We have applied three spectroscopic techniques (XAS, EPR and DRIFTS) in combination withe modulated excitation and catalytic data to decipher and propose the complete reaction mechanism of the simultaneous reduction of N2O and NO
