The electrochemical behaviour of magnetocaloric alloys La(Fe,Mn,Si)13Hx under magnetic field conditions

Abstract

The degradation mechanism of La(Fe,Mn,Si)₁₃H_x has been examined under conditions representative of the complex operating parameters of a refrigeration cycle. The magnetic field effects are found to be dominated by magneto-transport and are most significant when the material is in its paramagnetic state – resulting in significantly accelerated corrosion rates.
