Magnetoelectric effects in an organo-metallic quantum magnet [PDF]
, 2010 We observe a bilinear magnetic field-induced electric polarization of 50 $\mu C/m^2$ in single crystals of NiCl$_2$-4SC(NH$_2$)$_2$ (DTN). DTN forms a tetragonal structure that breaks inversion symmetry, with the highly polar thiourea molecules all tilted in the same direction along the c-axis. Application of a magnetic field between 2 and 12 T induces

The growth of 2D crystalline g-C3N4 films and the control of optoelectronic properties [PDF]
arXiv, 2023 g-C3N4 is a novel semiconductor photocatalyst material; however, the low specific surface area and rapid carrier compliance hinder its photocatalytic performance. On the other hand, the synthesis of 2D g-C3N4 with high crystallinity remains challenging.
