Rl. Sommer et al., BARKHAUSEN NOISE IN THE REENTRANT SYSTEM NI1-XMNX - A STUDY OF THE POWER SPECTRA, Journal of applied physics, 73(10), 1993, pp. 5497-5499
In this article, the power spectra of the Barkhausen noise of Ni1-xMnx
is presented. The measurements were made in the ferromagnetic phase a
t several temperatures and manganese concentrations in order to map th
e effects of the degree of disorder and of the temperature on domain w
all dynamics. Measurements in standard ferromagnetic materials were al
so made to compare the dynamics in both cases.
