Y3Fe5O12 exhibits a high magnon quality factor and low power loss, is a promising material for realizing quantum computers due to the long coherence time of its qubits. The five Fe3+ ions in Y3Fe5O12 represent spin-up and spin-down states, and substituting Fe3+ with other elements enables tuning of the magnon frequency. In this study, we grew single crystals of Y3Fe5−xGaxO12 (x = 0–1.0) and evaluated the changes in magnetic properties induced by Ga substitution.
