The ultrasonic velocity (nu_1) and attenuation coefficients (alpha) have been measured in mixed Mn-Zn ferrites at 2-, 3-, 5- and 10-MHz frequencies by Pulse Echo Overlap (PEO) method. Young's Modulus (E), isotropic compressibility (K_s), acoustic impedance (Z) and internal friction (Q~(-1)) are computed from experimental values of nu_1 and alpha. The variation of measured and computed parameters with change in frequency was reported.
