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（perovskite-like）甲酸铵骨架（ammonium formate frameworks）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），该体系因其……而受到广泛关注。
