TL;DR
This paper reports the successful growth of single crystals of Sm2Mo2O7, a metallic ferromagnet, and investigates its magnetic properties, supporting the hypothesis of an ordered spin-ice ground state.
Contribution
It introduces a method for growing large single crystals of Sm2Mo2O7 and provides detailed magnetic characterization relevant to its proposed spin-ice ground state.
Findings
Successful growth of large single crystals using the floating-zone method
Magnetization measurements along three axes
Support for the ordered spin-ice ground state hypothesis
Abstract
We have successfully grown cm3-size single crystals of the metallic-ferromagnet Sm2Mo2O7 by the floating-zone method using an infrared-red image furnace. The growth difficulties and the remedies found using a 2-mirror image furnace are discussed. Magnetization studies along the three crystalline axes of the compound are presented and discussed based on our recent proposal of an ordered spin-ice ground state for this compound
