Eng, Andrey O. Leonov, S\u00e1ndor Bord\u00e1cs, Martino Poggio and Istv\u00e1n K\u00e9zsm\u00e1rki report a magnetic state in GaV4Se8 which emerges exclusively in samples with mesoscale polar domains and not in polar mono-domain crystals.*<\/p>\n\n\n\n

It is manifested by a sharp anomaly in the magnetic susceptibility and the magnetic torque, distinct from other anomalies observed also in polar mono-domain samples upon transitions between the cycloidal, the N\u00e9el-type skyrmion lattice and the ferromagnetic states. *<\/p>\n\n\n\n

The authors ascribe this additional transition to the transformation of distinct magnetic textures, confined to polar domain walls (DW), to the ferromagnetic (FM) state. The emergence of these DW-confined magnetic states is likely driven by the mismatch of different spin spirals, hosted by the adjacent domains. A clear anomaly in the magneto-current indicates that the DW-confined magnetic states also have strong contributions to the magnetoelectric response. *<\/p>\n\n\n\n

The authors expect polar DWs to commonly host such confined magnetic edge states and, thus, offer a fertile ground to explore novel forms of magnetism. *<\/p>\n\n\n\n

To characterize the polar domains and to estimate the density of DWs in GaV4Se8, K. Geirhos et al. combined several complementary scanning probe microscopy techniques, including non-contact atomic force microscopy ( nc-AFM ), scanning dissipation microscopy ( SDM ), and frequency-modulated Kelvin-probe force microscopy ( KPFM ). *<\/p>\n\n\n\n

In attempt to observe spin cycloidal and N\u00e9el-type skyrmion textures within polar domains of GaV4Se8, only evidenced by small-angle neutron scattering measurements so far43, the authors of the article also carried out magnetic force microscopy (MFM) measurements. A second purpose of the MFM study was to explore possible magnetic states confined to the vicinity of DWs, as reported in GaV4<\/sub>S8<\/sub>. *<\/p>\n\n\n\n

NANOSENSORS\u2122 SSS-QMFMR<\/a> high resolution magnetic AFM probes<\/a> for ultra high vacuum conditions were used for the magnetic measurements with scanning probe microscopy. *<\/p>\n\n\n\n

NANOSENSORS\u2122 conductive wear-resistant Platinum Silicide AFM probes<\/a> of the PtSi-FM<\/a> type were used for all other measurements described in the article. *<\/p>\n\n\n\n

Typical ferroelectric do-main pattern observed on the (001) cleaved GaV4Se8 crystal surface\u00a0 atT=10\u00a0 K.
<\/strong>a, The topography is characterized by stripes roughly parallel to the [110] axis and folds parallel to the [010]\u00a0 axis. The latter originate in the differently oriented distortion of the ferroelastic domains. The color scale corresponds to the z-displacement of the tip.
b ,In the dissipation channel of the nc-AFM every second domain appears bright. For the non-magnetic tip the dissipation originates from electric interactions. The dissipated power is indicated by the color scale. Please have a look at the full article to view the full supplementary figure.<\/figcaption><\/figure>\n\n\n\n
