Magnetization‐Induced Second Harmonic Generation (MSHG) in a Pentacyanidonitrosylmolybdate‐Based Piezoelectric Ferrimagnet. Issue 12 (13th March 2018) - Komine, Masaya
Abstract : The pentacyanidonitrosylmetalate [ M (CN)5 (NO)] ( M = metal ion) is an attractive building block for bimetal assemblies exhibiting a long‐range magnetic ordering. In this work, a cyanido‐bridged bimetal assembly based on a pentacyanidonitrosylmolybdate, Cs1.26 Mn0.87 [Mo(CN)5 (NO)]· 0.6H2 O, was prepared. This compound has a noncentrosymmetric cubic crystal structure in the F 4 3 m space group and a lattice constant of 10.8970(3) Å. It exhibits ferrimagnetism with a Curie temperature ( T C ) of 65 K due to the antiparallel ordering of the Mn II ( S = 5/2) and Mo I ( S = 1/2) magnetic spins. Owing to the piezoelectric crystal structure, this compound exhibits second harmonic generation (SHG) and magnetization‐induced second harmonic generation (MSHG). Abstract : A molecule‐based magnet, Cs1.26 Mn0.87 [Mo(CN)5 (NO)]· 0.6H2 O, composed of pentacyanidonitrosylmolybdate, was synthesized. The compound has a piezoelectric crystal structure, which belongs to a noncentrosymmetric space group of F 4 3 m . The present compound shows a ferrimagnetism with T C of 65 K, and exhibits a SHG effect at room temperature and MSHG effect below T C .
