PRESSURE TUNING OF EXCHANGE COUPLINGS IN A FRUSTRATED MAGNET
Sergei Zvyagin, HLD Dresden. Spin-1/2 triangular-lattice Heisenberg antiferromagnets represent one of the most important classes of frustrated quantum magnets, demonstrating a complex interplay between geometrical frustration, quantum fluctuations, and magnetic order. In spite of their simple magnetic structures (Figure, inset), they possess highly unusual magnetic properties and a very [...]
