New magnetic intercalation compound of cyclic polyamine into MnPS_3

摘要

Two new inorganic-organic hybrid nanocomposite compounds were obtained by ion-exchange intercalation of hydroxylmesocyclic diamines (L_1) and 1,4,7,10-tetraazacyclo- tridecan-11,13-dione (L_2) into MnPS_3. The intercalation compounds were characterized by X-ray powder diffraction and infrared spectroscopy. The XRD indicated that the interlayer expansions were 3.58 A and 3.70 A respectively, suggesting that the cyclic planes were aligned parallel to the layer direction. The MnPS_3/L_2 intercalate exhibits spontaneous magnetization below 40K.
