We synthesized single crystals of composition Ba$_2$CuSi$_2$O$_6$Cl$_2$ and investigated its quantum magnetic properties. The crystal structure is closely related to that of the quasi-two-dimensional (2D) dimerized magnet BaCuSi$_2$O$_6$ also known a

N-Salicylideneaniline (SA) and its derivatives are known to exhibit photochromism, which is a reversible colour change induced by photo irradiation. Therefore, we performed on/off switching of the photochromic properties of an SA crystal by the hydra
