Discovery of spin glass in maple-leaf lattice Na2Mn3O7
Abstract
Geometrically frustrated magnetism is commonly studied in triangular and Kagome lattices. A rare lattice which exhibits frustration is obtained by depleting 1/7 of the sites from a triangular lattice and is called a maple-leaf lattice. We report the magnetic properties of an oxide material with a maple-leaf lattice: Na2Mn3O7. Structural studies suggest slight lattice distortion and density functional theory predicts energetic near-degeneracy between ferromagnetism and antiferromagnetic phases which points towards competing magnetic orderings at low temperatures. In addition, from our magnetic studies, we discovered a non-equilibrium spin state below ~50 K. The bifurcation of field-cooled and zero-field-cooled magnetization curves, hysteresis of ~16 kOe at 2 K, and time-dependent magnetization response is consistent with a spin glass state. To our knowledge this is the first report of such a state in materials with a MLL. This is a promising discovery towards using spin glass to transport angular momentum or spins for applications low power spintronics.
