Magnetic Emission During Austenite-Martensite Transformation in Ni₂MnGa Shape Memory Alloy

抄録

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 α and β respectively. The values of α and β are characteristic of the magnetic noise originating from the transition itself and both have the value of 3.0±0.15.
