Defects, impurities, and embedded particles in ferromagnetic materials are long known to be
responsible for the Barkhausen effect due to the jerky field-driven motion of domain walls …

This study investigates the phase transition of austenite into strain-induced martensite
during the long-term rolling contact wear. The transformation of the non-ferromagnetic …

Soft magnetic ferromagnetic/insulator composites are complex objects in terms of structure
and magnetic properties. They depend on many different parameters, among which one of …

We built a custom-made holder with a Hall-effect sensor to measure the single point
magnetic flux density inside a transmission electron microscope (TEM, JEM-F200, JEOL) …

The reactor pressure vessel (RPV) is a critical barrier in nuclear power plants, but its
embrittlement during service poses a significant safety challenge. This study investigated the …

A flame intensity sensor based on the resistive and memory properties of spintronic
memristor is proposed. The sensor circuit mainly consists of the infrared radiation …

Imaging methods and micromagnetic simulations have their own limitations. Despite using
multi-imaging techniques, it is probable that not all magnetic features can be visualized by …

This study deals with thermal burn during grinding cycles of two different roll-bearing steels,
case-carburised (CC) steel and 100Cr6 bearing steel, with different carbide structures …

The Materials Characterization research group at Tampere University started the
Barkhausen noise (BN) related studies in 1997. During the years, different aspects of the …
