Elastic behavior of some substituted Sr-Zn W-type hexagonal ferrites

In the present work, we investigate the elastic behavior of monovalent and divalent doped Sr-Zn W-type hexagonal ferrites at room temperature by measu ring their longitudinal and shear wave velocities using a pulse transmissio n technique. The values of Young (E) and rigidity (G) moduli have been corr ected to the theoretical density. The zero porosity values of both the elas tic moduli are found to increase with increasing dopant concentration. Furt her, a linear relationship between the Debye temperature and the average so und velocity has also been observed and the behavior is explained qualitati vely.
