Fe₃O₄ (Magnetite) Electronic Characterization

In this Educational Module, students will characterize the resistive properties of a sample of Fe₃O₄, more commonly known as magnetite. The primary emphasis will be to observe the Verwey transition, which is a structural phase transition accompanied by charge ordering.

Several items are needed for this experiment, which include:

• Magnetite sample
• Silver paint
• Silver paint applicator
• 25 micron diameter Pt or Au wire
• Apiezon N grease or GE7031 varnish
• Weighing or cigarette paper
• Tweezers
• Microscope
• Scissors
• Lighter
• Soldering iron
