Abstract
Magnetostriction measurements have been made on a series of compacted powder samples of oxide pigments used in magnetic recording, to provide information for the evaluation of the role of magnetostriction in the recording process. Two composition series were measured at 294 K: one from γFe2O3through a range of partial reductions to Fe3O4, and another from 0 to 4 at. % Co in γFe2O3; also samples of CrO2. In addition, a 2 at. % Co-doped Fe3O4powder was measured as a function of field and temperature from 77 to 300 K. Magnetostriction was measured using a semiconductor strain gage on a rotating sample, in fields up to 9 kOe.Keywords
