Abstract
The magnetic emission signals, accompanying the martensitic transition in Ni2MnGa magnetic shape memory alloy, are studied. The width (duration) and height (amplitude) distributions of the signals exhibit a power-law behaviour, with exponents (alpha) and (beta) respectively. The values of (alpha) and (beta) are characteristic of the magnetic noise originating from the transition itself and both have the value of 3.0(plus-minus) 0.15.
