Abstract
A working component for magnetic heat exchange comprises a magnetocalorically active phase comprising La.sub.1-aR.sub.a(Fe.sub.1-x-yT.sub.yM.sub.x).sub.13H.sub.z, a hydrogen content, z, 90% or higher of a hydrogen saturation value, z.sub.sat, and values of a, x and y selected to give a Curie temperature T.sub.c. M is one or more of the elements from the group consisting of Al and Si, T is one or more of the elements from the group consisting of Co, Ni, Mn, Cr, Cu, Ti and V and R is one or more of the elements from the group consisting of Ce, Nd, Y and Pr. T.sub.cmax is a Curie temperature of a La.sub.1-aR.sub.a(Fe.sub.1-x-yT.sub.yM.sub.x).sub.13H.sub.z phase comprising a hydrogen content z=z.sub.sat and said selected values of a, x and y. The working component comprises the T.sub.c wherein (T.sub.cmax-T.sub.c).ltoreq.20K.
