“…This spin-electric coupling in 1D compounds is very appealing for quantum information technology based on highly coherent spin systems. Considering oxides, magnetoelectric effects in 1D system was observed in a frustrated spin chain magnet SrCuTe 2 O 6 [191], however this (and many other oxide systems, like [192]) are not truly 1D magnetic systems, since at the lowest temperatures (below 5.5 K for this compound) a long range 3D order appears. Therefore, aforementioned metal-organic compound [187] is more close to the real 1D magnetic system owing it is magnetoelectricity to the anisotropic environment around the cobalt ions.…”

Solid state compounds exhibiting multiple and coupled macroscopic orders, named multiferroics, represent a challenge for both theoretical and experimental modern condensed-matter physics. Spins and the electric polarisation in conventional magnetic and ferroelectric materials can be manipulated on their fundamental timescales, by means of femtosecond laser pulses. In view of the resounding success and popularity of the all-optical approach, it is only natural to wonder about the application of this scheme to study the intrinsic coupling between spins and charges in multiferroics. Deeply fundamental questions arise: can ultrashort laser pulses deterministically activate, enhance or suppress the magnetoelectric coupling on the femtosecond timescale? Can these processes be triggered in a fully coherent fashion, thus being unrestrained by any thermal load? Which mechanism of spin-charge coupling is most favourable to overcome these overarching and daunting challenges? This problem is interdisciplinary in nature, requiring contributions from materials science and condensed matter physics from both theoretical and experimental perspectives. High-quality materials suitable for optical investigations have to be identified, synthetized and characterised. General and valid models offer then a guide to the plethora of possible light-induced processes, resulting in the desired ultrafast multiferroic manipulations. Finally, healthy experimental schemes, able to unambiguously track the ultrafast dynamics of either the ferroelectric or the magnetic order parameter have to be developed and implemented. Our motivation to write this review is to lay a broad and multidisciplinary foundation, which may be employed as a starting point for non-equilibrium approaches to the manipulation of the multiferroicity on the femtosecond timescale. This was also one of the main goals of the COST Action MAGNETOFON, whose network constitutes the core of the authors of this review. The present work thus represents a part of the scientific legacy of MAGNETOFON itself.

“…High-quality single crystals of Cu 3 TeO 6 were grown using HBr chemical transport method in sealed quartz tubes [26] and characterized using X-ray diffractometer at room temperature. Ferroelectric (FE) polarization hysteresis loops were obtained using a homemade Sawyer-Tower-type virtual ground setup [36] as described in [37] with frequency set to 77 Hz in quasi-static electric field up to 500 kV/m. Measurements were performed on bulk cuboidal samples with typical dimensions 1 × 1.5 × 3 mm 3 for three different orientations of magnetic field with respect to electric field in the temperature range from 10 to 75 K and magnetic field up to 12 T. The samples were mounted on a sample holder and inserted into a variable temperature insert of a 16 T Oxford superconducting magnet system.…”

We report on linear magnetoelectric effect observed by the static electric polarization measurements in external magnetic field up to 12 T on topological multidomain antiferromagnet Cu3TeO6. The polarization is non-zero only below the Néel temperature and for E ⊥ H. The magnetization data show spin reorientation taking place already in H < 1 T. This is fully captured by the anisotropic Heisenberg spin Hamiltonian, revealing the change of the magnetic point group from 3' in the ground state to m in the applied magnetic field, in agreement with the observed magnetoelectric effect. Both point groups allow the ferrotoroidic order which could be a source of magnetoelectric effect in this system. Our results establish Cu3TeO6 as a playground for the study of magnetoelectric topological antiferromagnets and a host of several phenomena which are of interest for future spintronic devices.
