Compressional and shear wave velocities and attenuation in magnetite, which was sintered in N_2 gas atmosphere, were accurately measured to investigate the Verwey transition by the pulse transmission method using a dual acoustic path across the temperature range between 78K and 300K. The temperature dependence of the compressional and shear wave velocities of the sintered magnetite exhibited a depression at 〜 85K. The low transition temperature corresponds to a large nonstoichiometry very close to the oxidation limit of magnetite. Using the measured ultrasonic data, the elastic properties of sintered magnetite are discussed. [DOI: 10.1143/JJAP.41.3176]
