Magnetic and magnetocaloric properties of R55Co30Al10Si5 (R = Ho, Dy) metallic glass ribbons

Structure, magnetism and magnetocaloric effects in Er5Si3B x (x = 0.3,0.6) compounds

“…[1][2][3][4][5][6][7] The novel solid-state refrigeration technology based on the magnetocaloric effect (MCE) is one of the most promising replacements for conventional refrigeration technologies because of its high efficiency and non-emission of pollutants. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] The MCE is the thermodynamic response of the magnetic material to an applied magnetic field, meaning that the magnetic moment transforms from ordered to disordered (or ordered to ordered) during the imposition of an applied magnetic field, resulting in a change in magnetic entropy. [24] The maximum magnetic entropy changes (−∆S max M ) generally appear near the magnetic phase transition temperature, so the magnetic phase transition is strongly correlated with the MCE.…”
