Abstract
The invention provides an alloy comprising e.g. manganese, iron, vanadium, phosphor and silicon. The invention also provides an apparatus comprising a magnetic field generator, a heat sink, the thermo element, a heat source, and a control system, wherein in a controlling mode the control system is configured to select between (i) a first configuration wherein the magnetic field generator generates a magnetic field, the thermo element is exposed to the magnetic field, and heat from the thermo element is transferred to the heat sink, and (ii) a second configuration, wherein the thermo element is not exposed to the magnetic field, and heat from a heat source is transferred to the thermo element.
