“…The spin spirals are often accompanied by an electrical polarization due to the presence of tilted spins breaking the inversion symmetry, which is a prerequisite for ferroelectricity 8–10 . For quasi one-dimensional spin-1/2 chain systems as LiCuVO 4 11–13 , LiCu 2 O 2 14 and PbCuSO 4 (OH) 2 15, 16 this ferroelectric (FE) polarisation were ascribed to a spin-driven improper FE effect at the three dimensional AFM ordering temperature 17–20 . The close coupling of magnetic order and electric polarization allows to switch the polarization by a magnetic field and to control via an electric field the spin helicity 21 .…”

Spin spirals, which coexist with collinear spin order in linarite PbCuSO4(OH)2, indicate electrical polarisation textures of spin-multipolar phases. We derive experimental evidence by a detailed investigation of the magnetic-field dependent dielectric and electric polarization properties at low temperatures. Linarite exhibits a quasi-one-dimensional frustrated S = ½ spin chain, which forms 3D spin-spiral order in zero magnetic field for T < 2.85 K. Recently, due to the monoclinic lattice of linarite with CuO2 ribbon chains, complex magnetic field induced states were found. These spin-multipolar phases, which compete with spin-density waves at low magnetic fields, exist in close vicinity to the transition from the spin spiral into field induced spin polarized state. Via antisymmetric Dzyaloshinskii-Moriya interaction spin-driven ferroelectricity develops in the spin-spirals state. Via electric polarization measurements this allows to prove the transitions into complex magnetic field induced phases. Thorough analyses of the temperature and magnetic field dependent dielectric properties of a naturally grown single crystalline sample provide a detailed (T,H) phase diagrams for the three different crystallographic directions.

“…Consequently, the saturation field is below 10 T, and the entire magnetic phase diagram of linarite is easily accessible with many experimental probes [179][180][181][182]. The frustration among J 1 and J 2 leads to a long-range elliptical-spiral ordering below the Néel temperature T N = 2.8 K, which causes electric polarization of the lattice and leads to a ferroelectric behaviour [183,184] manifested in signatures of T N in the dielectric constant, electric polarizability, and the pyroelectric and magnetoelectric current measurements [182]. Several other multiferroic phases can be stabilized in linarite by the application of magnetic field, resulting in the rich phase diagram depicted in Fig.…”

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.

“…Theoretically, a helical magnetic structure is expected for α (= -J 2 /J 1 ) > 1/4 (= α c ) within classical and quasi-quantum spin models [1]. Actually, LiVCuO 4 [2,3], LiCu 2 O 2 [4], and PbCuSO 4 (OH) 2 [5,6] with CuO 2 ribbon chains have helical magnetic order.…”

Neutron diffraction, magnetic susceptibility, and specific heat have been measured for polycrystalline samples of Li 2 ZrCuO 4 , in which quasi-one-dimensional quantum spin chains are formed from edge-sharing CuO 4 square planes called CuO 2 ribbon chains. Using neutron powder diffraction, an antiferromagnetic transition with incommensurate magnetic ordering has been found at T N ~ 7 K. Below T N , super-lattice magnetic reflections h k l±δ (h, k and l = even) with incommensurate modulation δ ~ 0.487 have been observed. This value for incommensurate modulation δ implies α (=-J 2 /J 1) = 6.2 on the basis of theoretical results from a J 1-J 2 classical spin model. This α-value contradicts α = 0.3 value reported by Drechsler et al. [Phys. Rev. Lett. 98, 077202 (2007)], which is close to the critical value α c = 1/4 for Li 2 ZrCuO 4 estimated from magnetic susceptibility data. The indices of magnetic reflection h k l±δ (h, k, and l =even) for Li 2 ZrCuO 4 indicate that the relation between nearest neighbor spin chains is "in-phase." It also indicates that inter-chain coupling is ferromagnetic, which differs from that for LiVCuO 4. On the basis of the obtained results, characteristics of the magnetic structure are discussed.
