2025 MRS Fall Meeting & Exhibit

Symposium SF02-Rare Earth Nitrides—From Fundamental Advances to Device Applications

The aim of the proposed symposium is to bring together different scientific communities who are contributing to the exciting and fast-growing field of the rare-earth nitride series of materials. The symposium will reflect the richness and push the frontiers of this field by incorporating topics spanning theoretical advances, epitaxial growth, emergent electronic properties, device and catalyst applications. The rare-earth (RE) ions, characterized by a partially filled 4f shell, have been recognized for some time as exploitable for their strong magnetic moments. Embedded in the NaCl structure of the mononitride, the REN offer a unique environment to study and exploit the magnetic properties of the RE elements where both the spin and unquenched orbital contributions to the magnetization can be leveraged. The rare confluence of a combined insulating and ferromagnetic ground state has gained the series interest from the superconducting spintronics community where such properties offer advanced functionality and speed in Josephson junction-based devices which will support superconducting and quantum computing. The present symposium will combine all aspects of the rare-earth nitrides and bring together theorists using these materials to develop computational and theoretical methods, the materials-scientists developing the growth and understanding of the magnetic- and electronic-properties and the experimentalists forming a new generation of superconducting logic and storage devices to support the next evolution of high-performance computing. A part of symposium will be also devoted to the emerging and multifaceted properties of the REN beyond spintronics applications. Discussion of fundamental material science, synthesis, fabrication routes and methods to support pressing opportunities related to the energy transition are encouraged. Particular attention will be paid to the use of REN as ammonia catalysts and in advanced nuclear fuel cycle applications.

Topics will include:

  • Thin films, nano and heterostructures
  • Advances in fabrication methods
  • Fundamental properties: magnetic, electronic, calorific, catalytic properties
  • Role of defects, impurity doping, interfaces and surfaces
  • Theory and modelling
  • Emerging phenomena (superconductivity, surface chemistry)
  • Applications: spintronics, superconducting electronics, thermoelectric devices, ammonia synthesis, nuclear fuel cycle
