Abstract
The potential difference and the frequency of Barkhausen jumps were measured in Li sub 0 sub . sub 5 sub + sub 0 sub . sub 5 sub x Ti sub x Fe sub 2 sub . sub 5 sub - sub 1 sub . sub 5 sub x O sub 4 (x < 0-0.07). In low range of magnetizing currents, Ti addition enhanced irreversible changes of magnetization. In high range of magnetizing currents, the potential difference showed a max value corresponding to a certain value of the magnetizing current.
