“…The third challenge is given by the magnetization process of the spin-1/2 KHAF. 26,27,[60][61][62][63][64][65][66][67][68] A series of magnetization plateaus at 3/9(= 1/3), 5/9 and 7/9 of the saturation is found, 26,65,66 among which the 1/3-plateau, already found by Hida, 60 is the widest. In addition to the above mentioned plateaus, there might be a tiny plateau at 1/9.…”

For the paradigmatic frustrated spin-half Heisenberg antiferromagnet on the kagomé lattice we performed large-scale numerical investigation of thermodynamic functions by means of the finitetemperature Lanczos method for system sizes of up to N = 42. We present the dependence of magnetization as well as specific heat on temperature and external field and show in particular that a finite-size scaling of specific heat supports the appearance of a low-temperature shoulder below the major maximum. This seems to be the result of a counterintuitive motion of the density of singlet states towards higher energies. Other interesting features that we discuss are the asymmetric melting of the 1/3 magnetization plateau as well the field dependence of the specific heat that exhibits characteristic features caused by the existence of a flat one-magnon band. By comparison with the unfrustrated square-lattice antiferromagnet the tremendous role of frustration in a wide temperature range is illustrated.

“…Accordingly a SS state is defined as a state having both the orders of the solid and the SF phases [35]. The search for SS phases has extensively been performed in recent years [36][37][38][39][40][41][42][43]. For example, the SS phases have been observed in SrCu 2 (BO 3 ) 2 with spin-1/2 Shastry-Sutherland lattice [40,41] and Cr spinel compounds with spin-3/2 pyrochlore lattice [42,43].…”

The Heisenberg model on a face center cubic (fcc) lattice is a typical three-dimensional frustrated spin system expected to have magnetization plateaus and supersolid phases. There are model compounds A2CoTeO6 (A = Ca, Sr, Pb) for the fcc lattice but with lattice distortions. Motivated by the presence of the compounds, we investigate the ground state of the spin-1/2 antiferromagnetic Heisenberg model on a tetragonally distorted fcc lattice in the magnetic field using a large-size cluster mean-field method for the sake of finding new supersolid phases. We find five supersolid phases in the model, indicating possibility to observe supersolid phases in these compounds. We also find that one of the supersolid phases is similar to the nonclassical coplanar phase obtained in the XXZ model on the triangular lattice.

“…Quantum fluctuations will give rise to exotic quantum superposition states of degenerate configurations, which can open up a way to novel quantum spin liquids at the magnetization plateaus. Indeed, various exotic plateaus have been found in quantum kagome magnets, 42,43) and extensive theoretical and numerical studies [44][45][46][47][48][49][50][51][52][53] have revealed that the formations of such plateaus are often attributed to the superstructures of magnons and/or valence bonds. In particular, the authors of Ref.…”

Field-Selective Classical Spin Liquid and Magnetization Plateaus on Kagome Lattice

We obtain a classical spin liquid (CSL) phase by applying a magnetic field to the J 1 -J 2 -J 3 Ising model on a kagome lattice. As we proved in the previous study [Phys. Rev. Lett. 119, 077207 (2017)], this model realizes one species of CSL, the hexamer CSL, at the zero magnetic field, which consists of macroscopically degenerate spin configurations with mixed total magnetization, M. The magnetic field selects its subset, which can be mapped to a trimer covering of the dual lattice and forms a magnetization plateau of M = 1/9. In addition to this CSL, we find two other magnetization plateaus at M = 5/9 and 17/27, which are ascribed to the "multimer" superstructures on a dual lattice.
