The low temperature phenomenology of Strontium Titanate is rich and intriguing, with anomalies producing signals of small intensity. We show that depolarization pyrocurrents are a suitable technique to greatly enhance these features, otherwise rather

Magnetic anisotropy is among the most important properties that are to be measured in permanent magnet characterization. While in single crystals it can be quite straightforwardly evaluated by conventional magnetometry, it often is of uncertain deter

Magnetic shape memory materials show outstanding and multifunctional properties (e.g. "giant" magnetomechanical, magnetocaloric, barocaloric), originating from the occurrence of both a martensitic transformation and magnetic order. Thin films and nan

In this study we have determined for first time the magnetic anisotropy field (HA) of Strontium Ferrite (SFO, SrFe12O19) nanoparticles of different morphologies using the Singular Point Detection (SPD) technique.

Ferromagnetic shape memory Heuslers show multifunctional properties arising from a strong coupling between magnetic, thermal and mechanical degrees of freedom. Within this class of compounds, Ni2MnGa is a model system, which shows a martensitic phase
