Doping-Dependent Spin Reorientation

In this Educational Module, students will synthesize and magnetically characterize samples of HoFeO₃ and HoCr_0.5Fe_0.5O₃.  HoFeO₃ undergoes a magnetic spin reorientation transition, and students will have the opportunity to investigate the effects of Cr doping on this phenomenon.

Several items are needed for this experiment, which include:

• Ho₂O₃, Fe₂O₃, and Cr₂O₃ Powder
• Balance
• Weighing Paper or Weighing Boats
• Spatula or Scoopula
• Mortar and Pestle
• Alumina Crucible
• Muffle Furnace
• Hydraulic Press
• Pellet Press Die
• Goggles, Nitrile Gloves, Safety Tongs, Thermal Gloves, and other PPE
