Investigation of magnetic phase transitions in the triangular lattice antiferromagnet Ca3NiNb2O9
Triangular lattice Antiferromagnets (TLAFs) exhibit intricate interplay of geometrical frustration, low dimensionality and small spin size leading to exotic magnetic ground states. Ca3NiNb2O9 has a triangular lattice with an isosceles motif, meaning that more exchange interactions are at play. This brings about at least 2 different magnetic order parameters, close-by in temperature. Further, we have succeeded in growing two distinctly different types of single crystalline Ca3NiNb2O9: as-grown and air-annealed and we propose here to study their magnetic ground state. Upon a successful experiment we plan to study an even more interesting high magnetic field phase (at H=10 T) in the near future.
