“…The most recent works focused on the multiferroic behaviour of francisite and the fieldinduced metamagnetic spin-flip transition to a ferrimagnetic structure, which has been observed at the critical field B c ≈ 0.8 T applied along the c axis [444]. The spins within every Cu plane are arranged in a commensurate noncollinear structure with a net FM polarization.…”

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. PACS: 75.30.-m -intrinsic properties of magnetically ordered materials; 75.10.Jm -models of magnetic ordering, including quantum spin frustration; 91.60.Pn -magnetic properties of minerals.

“…25,26 Moreover, some of the Cu 2+ -containing compounds have high spin ordering temperatures because of their strong superexchange interaction arising from Cu-O-Cu bonding. 27,28 A number of multiferroic/ME compounds with S = 1/2 chains were indeed found; LiCu 2 O 2 , 25 36 and KCu 3 As 2 O 7 (OD) 3 . 37,38 Most of these compounds listed in refs.…”

Magnetic field-induced ferroelectricity in S = 1/2 kagome staircase compound PbCu3TeO7

Ni 3 V 2 O 8 is an archetypical multiferroic material with a kagome staircase structure of S = 1 (Ni 2+ ) spins whose complex interplay between spin ordering and ferroelectricity has been studied for more than a decade. Here, we report a new kagome staircase compound PbCu 3 TeO 7 with Cu 2+ (S = 1/2) spins that exhibits two Néel temperatures at T N1 = 36 K and T N2 = 24 K, and a magnetic field (H)-induced electric polarization (P) below T N2 . Pyroelectric and magnetoelectric current measurements in magnetic fields up to 60 T reveal that for H||c of~8.3 T, a spin-flop transition induces a transverse P||a with a magnitude of 15 µC/m 2 below T N2 . Furthermore, for a parallel configuration with P//H//a, two spin-flop transitions occur, the first at~16 T with P//a of 14 µC/m 2 , and the second at~38 T, where P disappears. Monte Carlo simulations based on 12 major exchange interactions uncover that a sinusoidal amplitude modulation of the spins occurs along the b-axis below T N1 and an incommensurate, proper screw-type spin order occurs in the ac-plane below T N2 . The simulation results show that P//a under H//c stems from a spin-flop transition facilitating an ab-plane-type spiral order, while the two successive spin-flop transitions for H//a result in spiral spin orders in the aband bc-planes. Based on the experimental and theoretical results, we establish field-induced magnetic and electric phase diagrams for the two H directions, demonstrating that the distorted kagome staircase structure with competing intra-interlayer interactions and lifted frustration creates a plethora of different noncollinear spin textures of S = 1/2 spins that in turn induce electric polarization.

“…Many research groups contributed to the studies of the microscopic magnetic structure of the synthetic francisites. These fruitful structural, electromagnetic, and optical studies combined with the theoretical calculations resulted in discoveries of some interesting features of the francisite-like compounds [49][50][51][52][53][54][55][56][57][58][59][60][61]. Thus, a structural transition was detected in Cu 3 Bi(SeO 3 ) 2 O 2 Cl, but surprisingly it was not observed in Cu 3 Bi(SeO 3 ) 2 O 2 Br.…”

“…Thus, a structural transition was detected in Cu 3 Bi(SeO 3 ) 2 O 2 Cl, but surprisingly it was not observed in Cu 3 Bi(SeO 3 ) 2 O 2 Br. Moreover, the origin of this transition is still not clear [59][60][61]. The most recent publications suggest spin-flip-induced multiferroic behavior in Cu 3 Bi(SeO 3 ) 2 O 2 Cl [57,59] and this might be a consequence of a structural transformation.…”

Transition Metal Selenite Halides: A Fascinating Family of Magnetic Compounds

The problem of searching for low-dimensional magnetic systems has been a topical subject and has attracted attention of the chemistry and physics community for the last decade. In low-dimensional magnetic systems, magnetic ions are distributed anisotopically and form different groups such as dimers, chains, ladders, or planes. In 3D frameworks, the distances between magnetic ions are equal in all directions while in low-dimensional systems the distances within groups are different from those between groups. The main approach of searching for desired systems is a priori crystal chemical design expecting the needed distribution of transition metal ions in the resulting structure. One of the main concepts of this structural design is the incorporation of the p-element ions with stereochemically active electron pairs and ions acting as spacers in the composition. Transition metal selenite halides, substances that combine SeO 3 2− groups and halide ions in the structure, seem to be a promising object of investigation. Up to now, there are 33 compounds that are structurally described, magnetically characterized, and empirically tested on different levels. The presented review will summarize structural peculiarities and observed magnetic properties of the known transition metal selenite halides. In addition, the known compounds will be analyzed as possible low-dimensional magnetic systems.
