In this research, the evolution of piezomagnetic field a low carbon steel under cyclic tensile stress was investigated. The objective to explore correlations between signal measured by fluxgate magnetometer with progressive changes that take place during fatigue tests. Experiments show first hysteresis loop drastically propagation crack. A multiscale magneto-elastic model behavior allows second...

The appearance of magnetization during the application mechanical stress and creation elastic deformation a magnetic field are two fundamental properties piezomagnetic materials. symmetry superconducting ferromagnets UGe_2, URhGe, UCoGe allows piezomagnetism. In addition to conventional occurring in both normal states, state these piezomagnets has its own specificity. Unlike superconductors, ur...

Abstract Actinide materials exhibit strong spin–lattice coupling and electronic correlations, are predicted to host new emerging ground states. One example is piezomagnetism magneto-elastic memory effect in the antiferromagnetic Mott-Hubbard insulator uranium dioxide, though its microscopic nature under debate. Here, we report X-ray diffraction studies of oriented dioxide crystals pulsed magnet...
