Abstract
The magnetostriction of Fe3O4 was measured, using the strain gauge technique. Two methods were used to measure the magnetostrictive behavior of single crystals and polycrystalline samples as a function of orientation and temperature. The measurements show that magnetostriction does not play an important part in causing a peak in initial permeability in magnetite near its low-temperature transition. Another conclusion is that magnetostriction measurements can be used for this type of material as a tool to detect changes in the direction of easy magnetization.
