Magnetic Properties of Lithium-Containing Rare Earth Garnets Li3RE3Te2O12 (RE = Y, Pr, Nd, Sm-Lu)

TL;DR

This paper investigates the magnetic properties of a series of lithium-containing rare earth garnets, detailing their synthesis, structure, and magnetic behavior across different rare earth elements, highlighting notable behaviors in specific members.

Contribution

It provides the first comprehensive study of the magnetic susceptibilities and magnetizations of Li3RE3Te2O12 garnets across multiple rare earth elements, including structural refinement for Li3Dy3Te2O12.

Findings

Magnetic susceptibilities vary with temperature and rare earth element.

Some garnets exhibit saturation magnetization at 9 Tesla and 2 K.

Behavior of Pr, Tb, Dy, and Yb garnets is particularly notable.

Abstract

The synthesis, structural description, temperature dependent magnetic susceptibilities and field dependent magnetizations of a series of rare earth garnets of the form Li3RE3Te2O12 (RE = Y, La, Pr, Nd, Sm-Lu) are reported. The structure of Li3Dy3Te2O12 is refined from powder X-ray diffraction data. The field dependent magnetizations saturate for some of the members by 9 Tesla at 2 K. Of particular interest for further study in this family is the behavior of the Pr, Tb, Dy and Yb garnets.
