Probing the ground state magnetic structure of single crystalline Ho3Fe5O12, (Ho,Y)3Fe5O12 and Lu3Fe5O12

Lu and Ho counterparts of RE3Fe5O12 will be an appropriate platform to reveal the complexmagnetic ground state of rare earth iron garnets with common formula RE3Fe5O12. Lu3+ doesnot possess magnetic moment due to the absence of unpaired electrons with 4f^14 electronicconfiguration, but Ho3+ possesses finite magnetic moment for having 4f^10 ground stateconfiguration. 50% Y doping at Ho site reveals new magnetic transition. Hence, studying these compounds together will explore the role of rare-earthmoment in the magnetic ground state of these garnets. No definitive work on single crystal neutrondiffraction study on these compounds has been performed so far. Hence, a detailed study onmagnetic ground states of these garnets is owed to plant to get insight into the fundamentalphysics and single crystal neutron diffraction is the best technique for this investigation.
