ABSTRACT
The velocity of longitudinal and transverse sound waves was measured between 77 and 300 K and used to determine the Young modulus, the shear modulus, and the adiabatic compressibility of the polycrystalline, strong permanent magnet compound, Nb2Fe14B. The spin reorientation occurring near 150 K appears as an anomaly in the temperature dependence of the elastic moduli. The ΔE effect is of the order of 0.5% at 77 K.
