​The Centre for Superconductivity, Spintronics and Surface Science (C4S) is a research centre witihin the ​Technical University of Cluj-Napoca (member of the EUt+ consortium). Within EUt+, the C4S research staff have recently become part of the European University of Technology Institute of Nanomaterials and Nanotechnologies, EUTINN.
The Centre has longstanding expertise in superconducting, magnetic, and oxide thin films grown both by physical and chemical methods. Within the Superconductivity axis, the major topic relates to the YBa2Cu3O7 high-temperature superconducting epitaxial thin film fabrication technology using chemical methods and related topics: oxide buffer layer templates, artificial pinning centers and flux pinning studies. The second topic, Spintronics and Spinorbitronics, involves thin film elaboration, device patterning, magneto-opto-electric characterization, to fabricate and study novel devices by employing materials with tailored interface functionalities. The Materials Chemistry research axis focuses on the synthesis of a wide area of complex materials in different forms (thin films, nano-particles, powders). They cover a large spectrum of applications including, but not restricted to superconductivity and magnetism. Since the Center focuses on developing systems with reduced dimensionality, i.e., thin films and nano-particles, Surface Science is an intrinsic aspect of our research.
