Abstract
Measurements of magnetically induced velocity changes in polycrystalline nickel rods are discussed. Shear and compressional ultrasonic propagation modes are used throughout the frequency range of 1–10 megacycles. The polycrystalline measurements are compared to recently published single nickel crystal values. The ΔE effect is found to decrease with increasing frequency throughout the megacycle region, showing general agreement with low frequency measurements.Keywords
