Effect of quenching on the magnetic properties of Mg-ferrite thin films
Source abstract
Abstract
We have investigated the microstructural and magnetic properties of the post annealed slow cooled and quenched Mg-ferrite thin films. The microstructural properties of these films were studied through XRD, TEM and SEM. The magnetic properties were studied using VSM at 300K and 10K. The quenched film showed ∼1.66 times higher magnetization at room temperature (RT) compared to the bulk and the slow cooled film (4πMS of bulk∼1880 Gauss at RT) though the crystal phase, grain size and thickness of both the films were similar. The change in the cation distribution is the plausible origin of large magnetization observed in the quenched (rapid cooled) film.
