Ni0.7Zn0.3Fe2O4 nanoparticles (9-42 nm) were synthesized by low-temperature solid-state reaction (LTSSR) method. Transmission electron microscopy (TEM) and X-ray diffractometer (XRD) were used to analyze the structural properties. It was found that the particle size and magnetic properties of the prepared ferrite sample showed strong dependence on the annealing temperature. The coercivity initially increased and then decreased with increasing the annealing temperature whereas the particle size and saturation magnetization continuously increased. Q-Factor (quality factor) of Ni0.7Zn0.3Fe2O4 was measured by LCR-Meter which was constant and maximum in the broad band frequency from 0.5 to 3 MHz..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
