Ferroelectric transitions in potentially multiferroic Mn-formate frameworks

The perovskite-like family of ammonium formate frameworks AB(HCO2)3, where A is a divalent metal ion and B is an (alkyl)ammonium or guanadinium, is of great interest for its...类钙钛矿型甲酸铵骨架家族AB(HCO₂)₃，其中A为二价金属离子（divalent metal ion），B为烷基铵（alkylammonium）或胍鎓（guanadinium），该类材料因……而受到广泛关注。
