Discovery Teaching Labs - Doping-Dependent Spin Reorientation

Doping-Dependent Spin Reorientation
PPMS® VersaLab®

In this Educational Module, students will synthesize and magnetically characterize samples of HoFeO3 and HoCr0.5Fe0.5O3. 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
