Thermodynamic studies of new triangular lattice Ytterbium selenites

Magnetic materials with frustrated lattices draw significant attention in the search for unusual phenomena such as quantum spin liquid (QSL), in which the magnetic moments are strongly correlated, and yet no long-range magnetic ordering develops at very low temperatures due to geometric frustration. Triangular lattice (TL) antiferromagnetic systems are widely explored for QSL because of their simplicity of lattice arrangement. In Heisenberg two-dimensional TL systems (S = ½), the quantum fluctuations are more robust, which suppresses long-range magnetic order (LRO) even at T = 0 K limit. We synthesized and studied the thermodynamic properties of a new family of triangular lattice Ytterbium (Yb) selenites. These results demonstrate the absence of long-range ordering down lowest temperature accessible. In this talk, we are going to present our experimental results for this triangular lattice Yb selenites.
