“…Further, the frustration can be partially relieved by structural distortions [279][280][281] or disorder [282,283], precluding a spin-liquid ground state. For instance, a low-temperature ordered state is found in volborthite, [284][285][286], and vesignieite, [287], which has been explained by the non-equivalent exchange on the triangles forming a distorted kagome lattice as a result of orbital ordering [288,289]. In this chapter, we discuss the specific behaviour of various minerals realizing different magnetic models on the kagome lattice.…”

“…Its monoclinic distortion was initially considered small enough to keep the essential physics. However, it soon became clear that volborthite orders antiferromagnetically at temperatures near 1 K [284,285]. In magnetic fields above B s1 ≈ 4.5 T, a second ordered phase (phase II) with a coplanar cycloidal structure forms, persisting to B s2 ≈ 25.6 T, where it gives way to a high-field collinear ferrimagnetic phase (phase III) with a much higher ordering temperature of ∼ 26 K [286,398].…”

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of lodestone -a magnetized version of the mineral magnetite. Nowadays, natural minerals continue to inspire the search for novel magnetic materials with quantum-critical behaviour or exotic ground states such as spin liquids. The recent surge of interest in magnetic frustration and quantum magnetism was largely encouraged by crystalline structures of natural minerals realizing pyrochlore, kagome, or triangular arrangements of magnetic ions. As a result, names like azurite, jarosite, volborthite, and others, which were barely known beyond the mineralogical community a few decades ago, found their way into cutting-edge research in solid-state physics. In some cases, the structures of natural minerals are too complex to be synthesized artificially in a chemistry lab, especially in single-crystalline form, and there is a growing number of examples demonstrating the potential of natural specimens for experimental investigations in the field of quantum magnetism. On many other occasions, minerals may guide chemists in the synthesis of novel compounds with unusual magnetic properties. The present review attempts to embrace this quickly emerging interdisciplinary field that bridges mineralogy with low-temperature condensed-matter physics and quantum chemistry.

“…Third, we cannot see a non-bonding band that should appear together with bonding and antibonding bands for triple layer compounds when the many body effect is weakened. double layer cuprates [31][32][33]. In other words, a strong enhancement of the energy gap towards (,0) is considered as evidence that this band is for the underdoped state.…”

We discuss the characteristic features of triple Cu-O2 layer cuprates superconductors, by comparing those of single and double layer cuprates superconductors. After a brief introduction to multilayer cuprates and their characteristic properties such as the doping imbalance between the inner and outer Cu-O2 planes (IP and OP, respectively) revealed by nuclear magnetic resonance, we present the experimental results of angle resolved photoemission and Raman scattering spectroscopy for the triple layer Bi2Sr2Ca2Cu3O10+z which showed two different superconducting gaps opening on the IP and OP.The doping dependence of the double peak structure in Raman spectra was found to be qualitatively consistent with that of single and double layer cuprates, if each layer doping for the IP and OP is taken into account. The fact that the IP and OP share the same electronic phase diagram and the same transition temperature (Tc) hints to a coupling between the IP and OP. Moreover, the energies of IP and OP Raman peaks were found to be very large, not scaling with Tc, which can be attributed to the strong influence of the pseudogap of the underdoped IP in triple layer cuprates. These findings suggest that the high Tc and the large gap ratio of triple layer cuprates are realized through a combination of the interlayer coupling between the OP and IP and the interaction between superconductivity and the pseudogap.

“…In this normal-state case, the interplay of the CDW order with superconductivity disappears, leading to that the novel hidden PDW order is therefore absent in the normal-state. Finally, we emphasize that since the CDW gap in the Hamiltonians (3) and (7) has been identified as the pseu-dogap∆ PG , this is also why the CDW order exists within the pseudogap phase, appearing below a temperature of the order of T * well above T c in the underdoped regime, and coexists with the hidden PDW order and superconductivity below T c 11-23 . In conclusion, within the framework of the kineticenergy-driven superconductivity, we have studied the physical origin of the PDW order in cuprate superconductors and of its connection with the interplay of the CDW order with superconductivity by taking into account the pseudogap effect.…”

When the Mott insulating state is suppressed by charge carrier doping, the pseudogap phenomenon emerges, where at the low-temperature limit, superconductivity coexists with some ordered electronic states. Within the framework of the kinetic-energy-driven superconductivity, the nature of the pair-density-wave order in cuprate superconductors is studied by taking into account the pseudogap effect. It is shown that the onset of the pair-density-wave order does not produce an ordered gap, but rather a novel hidden order as a result of the interplay of the charge-density-wave order with superconductivity. As a consequence, this novel hidden pair-density-wave order as a subsidiary order parameter coexists with the charge-density-wave order in the superconducting-state, and is absent from the normal-state.
