Abstract

Experimental results concerning the scalar piezomagnetic coefficients of Co-based ferrites at room temperature are presented and discussed. To increase the mechanical properties, the ferrite powders are bonded by a phenol-based matrix. The Young's modulus of the samples is about 8 GPa. The permeability of the samples μ_z^σ ( H ) and the slope of magnetostriction curve d₃₃^σ ( H ) at constant stress, which are the most important piezomagnetic coefficients for stress sensing and mechanical actuation, are discussed in detail with respect to sample density changes due to different content of binder and compaction pressure.
