The Greater Copenhagen Nanoscience Seminar

Within a radius of just 25 km, the Copenhagen-Lund region features three strong hubs for nanoscience, with complementary strengths, scientific focus and capabilities:

• the Nano-Science Center at the University of Copenhagen
• NanoLund at Lund University
• a cluster of groups at the Technical University of Denmark

Each hub comprises more than 30 research groups from several disciplines and several hundred staff, has developed advanced facilities for synthesis, characterization and fabrication of nanostructures, has a strong track record in translating discoveries into new technologies, and each is heavily engaged in education at all levels.

Our joint vision is to discover, invent and develop nanosystems with functionalities that emerge from the designed interaction between highly controlled and tunable building blocks.

By combining highly controlled building blocks from very different material systems to realize advanced, functional systems, we aim to jointly address challenges that are out of reach for an individual center.

The aim of this seminar series is to increase awareness about our mutual capabilities and to inspire collaborations.

Scheduled talks and topics

24^th February 2023 at 15:15 - Magnetic nanomaterials

There will be three speakers, one from each hub (Copenhagen University, DTU and NanoLund).

Speakers, talk titles and short descriptions

Stergios Piligkos (KU): Quantum coherence in molecular Lanthanide complexes

In this seminar entitled “Quantum coherence in molecular Lanthanide complexes” I will present the work done in my group relevant to coherent dynamic magnetic properties of electronic and nuclear spins in lanthanide-based molecular materials. I will present the potential of molecular magnetic materials for use as physical support for the implementation of quantum bits for Quantum Technologies, as well as a scheme for intrinsic implementation of quantum error corrections in these systems.

Rasmus Westerström (ULUND): Template-free generation of magnetic nanostructures by directed self-assembly of nanoparticles

In this seminar, I will present a template-free technique for generating 1D, 2D, and 3D magnetic nanostructures by directed self-assembly of magnetic nanoparticles. I will demonstrate how single-component and segmented nanowires and multi-component structures can be generated and present a magnetization study using SQUID magnetometry and X-ray microscopy. The self-assembly can take place on any substrate, allowing for direct integration into different device architectures. The latter is demonstrated by presenting transport measurements performed on single nanowires directly self-assembled and contacted onto a pre-patterned Si-chip.

The format will be 15 + 5 for the two speakers and then a general discussion.
