The Superconductor Science and Technology journal included the article entitled “Investigation of all niobium nano-SQUIDs based on sub-micrometer cross-type Josephson junctions” in its collection of 2015 highlights. Dr. Matthias Schmelz, an employee at the Leibniz Institute of Photonic Technology (IPHT) in Jena and the lead author of the publication, received a certificate for this contribution at the Applied Superconductivity Conference held in Denver, Colorado, U.S.A. This certificate confirms the significant importance of the publication in this field.
