The magnetic properties of steels are affected by plastic deformation, because the domain wall processes magnetoelastically interact with the dislocations and the residual stresses. The evolution of the magnetic hysteresis loop and its parameters wit

In this paper we investigate the entropy change and the kinetics at the magneto-structural transition (at 628 K) of polycrystalline MnBi. Samples were prepared by rapid quenching and annealing and exhibit 86 wt% of the hexagonal MnBi phase. The entro

In this paper we discuss measurements of the heat exchanged along the hysteresis loop and the return branches of barium ferrite of composition BaFe 12 O 19 . The measurements show the joint presence of a dissipated heat, connected with the hysteresis

We discuss Barkhausen noise experiments performed in interstitial-free low-carbon steel laminations, subjected to increasing deformation either by tensile straining or cold rolling. The spectral density of the noise, measured under a constant magneti

Interstitial-free (IF) low carbon steel laminations have been subjected to plastic deformation either by tensile straining or cold rolling and their magnetic hysteresis behavior has been investigated for permanent elongation up to approximately 6%. W
