Managing refrigeration of our homes, our food and our work environments in energy efficient ways is of increasing importance. Refrigeration using solid state magnetic cooling is one of a number of technologies that may make a significant contribution to addressing this problem. In order to develop materials that may enable commercial development of this increasingly relevant field it is important to review the reliability of methods used to extract key physical properties, so that as the field matures the community can develop recognised standards of measurement. Here we measure key physical properties in one composition taken from a series of La(Fe,Si,Mn)Hδ 1:13‐type samples grown by a source laboratory and measured independently in a consortium of European laboratories using both commercial and bespoke facilities.
The research leading to these results has received funding from the European Community's 7th Framework Programme under grant agreement no. 214864 (“SSEEC”). K.G.S. acknowledges financial support from The Royal Society.
