Temperature dependence of the antiferromagnetic resonance spectrum in a thulium orthoferrite (TmFeO3) poly-crystalline sample was studied by transmission spectroscopy frequency range 0.1–0.75 THz and temperature 300–670 K, up to its Néel temperature. We observed quasi-ferromagnetic quasi-antiferromagnetic modes. The frequencies, linewidths, amplitudes were extracted. TmFeO3 near directly drasti...

In recent years, TRIP/TWIP steels have been the focus of great attention thanks due to their excellent tensile strength-ductility combination. The compression tests were performed at different temperatures from 25 to1000°C to study the mechanical behavior of advanced austenitic steel with 21% manganese plus bearing Ti. The results indicated that the plastic deformation is controlled by deformat...
