Scientists have produced a new route to materials with complex 'disordered' magnetic properties at the quantum level. The material, based on a framework of ruthenium, fulfils the requirements of the 'Kitaev quantum spin liquid state' -- an elusive phenomenon that scientists have been trying to understand for decades.
Scientists have produced a new route to materials with complex 'disordered' magnetic properties at the quantum level. The material, based on a framework of ruthenium, fulfils the requirements of the 'Kitaev quantum spin liquid state' -- an elusive phenomenon that scientists have been trying to understand for decades.
Quantum spin liquid materials have magnetic properties that don't behave in that way. Instead of the well-ordered characteristics of ferromagnets, these materials are disordered and the electrons within them connect magnetically via a process called quantum entanglement. Lead researcher Dr Lucy Clark explains:"This work is a really important step in understanding how we can engineer new materials that allow us to explore quantum states of matter. It opens up a large family of materials that have so far been underexplored and which could yield important clues about how we can engineer new magnetic properties for use in quantum applications."
It is thought this behaviour is connected to the densely packed crystal structures of candidate materials. Because the ions are packed so closely together they are able to interact directly with each other, resulting in them reverting to magnetic order. "While this work has not led to a perfect Kitaev material, it has demonstrated a useful bridge between theory in this field and experimentation, and opened up fruitful new areas for research," added Dr Clark.Aly H.
