STUDY AND MATERIAL DEVELOPMENT OF MAGNETOSTRIC TIVE FERRITE ELEMENT.

Abstract

A study has been made of the ferrite system Mn(x)Fe(1-x)Fe2O4 as materials for magneto strictive transducer applications. A region of compositions in this system exhibits coupling coefficients in excess of 30% with a maximum value exceeding 50%. A beginning was made in the reduction of the electrical conductivity of the composition possessing this maximum in the coupling coefficient. A detailed electromechani cal analysis of this latter material is reported. Similar detailed studies are given for Co0.01 Fe0.99Fe2O4 and for FeFe2O4. In certain of the more (electrical) conducting materials eddy cur rent effects are observed. (Author)
