Hans-Joachim Grafe

Dr. Hans-Joachim Grafe is a group leader at the Institute for Solid State Research within the Leibniz Institute for Solid State- and Materials Research (IFW Dresden) in Germany. His research focuses on Nuclear Magnetic Resonance (NMR) studies of quantum materials, particularly investigating high temperature superconductors and quantum magnets.

Dr. Grafe completed his diploma thesis at TU Braunschweig on NMR measurements of Sr₁₄Cu₂₄O₄₁ under the guidance of Hans-Henning Klauß. He then pursued his PhD at IFW Dresden and TU Dresden, working with Bernd Büchner and Nicholas Curro at Los Alamos National Laboratory on NMR studies of rare earth co-doped lanthanum cuprates.

His research interests span Nuclear Magnetic Resonance spectroscopy, high temperature superconductivity, quantum magnetism, and the development of novel NMR instrumentation. Dr. Grafe has made significant contributions to understanding the electronic and magnetic properties of unconventional superconductors using NMR techniques. Recently, he has been involved in developing self-assembled rolled-up microcoils for NMR on nanoliter-sized samples, expanding the capabilities of NMR spectroscopy for studying minute quantities of materials.

Analysis of Dr. Grafe's recent publications (2021-2025) reveals a strong focus on applying NMR techniques to investigate quantum magnetic systems, high-temperature superconductors, and novel instrumentation development. His work spans condensed matter physics, materials science, and NMR methodology, with particular emphasis on frustrated magnets, iron-based superconductors, and innovative approaches to enhance NMR sensitivity for nanoscale applications.

Dr. Grafe has presented his research at numerous international conferences and seminars, including the Mitteldeutsches Resonanztreffen, Analytica, and various university seminars across Europe. His invited talks often focus on NMR applications in quantum materials and recent advances in NMR instrumentation.
