Abstract
Abstract The focus of this study is on the magnetic properties of the very recently synthesized doubly ordered perovskite family NaLnCoWO6 (Ln = Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, and Yb). Magnetic characterizations were performed by magnetic susceptibility vs. temperature, isothermal magnetization and heat capacity measurements. All these compounds have been determined as antiferromagnets with Neel temperatures from 4 K to 13.1 K. When the lanthanide is magnetic, additional transitions were observed below the Neel temperature which are attributed to the polarization of the magnetic Ln3+ sublattice by the ordered Co2+ one. Taking into account the magnetic ordering found in this study and the polar structure in the nine compounds NaLnCoWO6 (Ln = Y, Sm, Eu, Gd, Tb, Dy, Ho, Er, and Yb) reported before, these compounds can be classified as new Type I multiferroics.
