Heterogeneous nucleation and heat flux avalanches in La(Fe,Si)${}_{13}$ magnetocaloric compounds near the critical point

C. Bennati, L. Gozzelino, E. S. Olivetti +1

The phase transformation kinetics of LaFe${}_{11.41}$Mn${}_{0.30}$Si${}_{1.29}$-H${}_{1.65}$ magnetocaloric compound is addressed by low rate calorimetry experiments. Scans at 1 mK/s show…
