WebIntroduction Hexagonal Fe 2 P-type transition metal FeMn-based magnetocaloric materials (FeMnP 1−x T x, T = As, Si, Ge) are driving tremendous research interest because of their promising application in solid-state refrigeration as energy efficient, environment friendly alternative to the traditional gas-compressor based cooling scheme. 1–9 This family of … WebFeb 10, 2014 · This is similar to current refrigeration technology that uses a compressor to move heat, but using magnets could make refrigeration 20 percent more energy efficient.

Magnetic fridge eliminates gases, drastically reduces energy use

WebRecent work has yielded new insights into the thermodynamic operation of active magnetic regenerative refrigerators (AMRR’s). Existing theory specifies a linear profile of adiabatic magnetization temperature change (ΔT ad) with temperature (T) of the material in the flow direction of the regenerator.This theory is shown here to be incorrect because an AMRR … WebAn experimental study of the rotational magnetocaloric effect in Ni(en)(H2O)4SO4∙2H2O (en = ethylenediamine) single crystal is presented. The study was carried out at temperatures above 2 K and was associated with adiabatic crystal rotation between the easy plane and hard axis in magnetic fields up to 7 T.
