“…The isothermal magnetic entropy change DS m has been reported for Fe-based amorphous ribbons with T C ranging from temperatures below 200 K [111,112] to T > 600 K [113,114]. Considerable attention has been paid to the influence of the addition of ferromagnetic Co or Ni [106,[114][115][116][117][118] or antiferromagnetic Cr or Mn [107,[111][112][113][119][120][121][122][123] on magnetic properties and MCE of Fe-based ribbons. When Fe is substituted by Co or Ni, the Curie temperature T C of the Fe-based amorphous ribbons was found to increase significantly [115,116,118].…”

“…Considerable attention has been paid to the influence of the addition of ferromagnetic Co or Ni or antiferromagnetic Cr or Mn on magnetic properties and MCE of Fe‐based ribbons. When Fe is substituted by Co or Ni, the Curie temperature T C of the Fe‐based amorphous ribbons was found to increase significantly . This tendency was explained by the assumption that Fe–Co (Fe–Ni) exchange interactions are stronger than Fe–Fe ones .…”

Room temperature magnetic refrigeration is an energy saving and environmentally‐friendly technology, which has developed rapidly from a basic idea to prototype devices. The performance of magnetic refrigerators crucially depends on the magnetocaloric properties and the geometry of the employed refrigerants. Here we review the magnetocaloric properties of Heusler alloys and related compounds with a high surface to volume ratio such as films, ribbons, and microwires, and compare them with their bulk counterparts.

“…Other researches focused on perovskite manganites with a general formula RE 1−x AE x MnO 3 after the observing large magnetocaloric effects (MCE) in these compounds [14][15][16][17]. Currently, MCE offers an alternative technology in refrigeration, with an enhanced efficiency but without environmental hazards [18][19][20][21]. The key in using magnetic refrigeration at room temperature is to seek the proper refrigerant materials which can produce a large entropy variation when it goes through a magnetizationdemagnetization process.…”

Morphology, magnetic and magnetocaloric properties of La 0.62 Er 0.05 Ba 0.33 Mn 1−x Fe x O 3 (x = 0.00, 0.05 and 0.15) were experimentally investigated. Solid-state reaction method was used in the preparation of the samples. The microstructure of the samples was determined by scanning electron microscopy (SEM). From the XRD study, it has been found that all samples are single-phased and crystallized in the rhombohedral structure with the R3-c space group. For x = 0.05 and 0.15, a steep drop of zero field-cooled (ZFC) magnetization at low temperature signifies the formation of cluster-or spinglass state. This is caused by the competition between the ferromagnetic and antiferromagnetic interaction. A sensitive response to substituting Fe for Mn is observed in the magnetic and magnetocaloric properties. We found that Fe doping is powerful enough to reduce Curie temperature T C and it brings about cluster glass behaviours. The magnetocaloric effect is calculated from the measurement of initial isothermal magnetization versus magnetic field at various temperatures. The maximum entropy change S max M reaches the highest values of 3.31, 3.12, and 2.57 J/kg K in magnetic field. However, the relative cooling power decreases with Fe content from x = 227.44 to 188.68 J/kg for x = 0.00 to x = 0.15 compositions, respectively.

“…Magnetic refrigeration based on the MCE can effectively reduce environmental impact when compared with the conventional gas compression-expansion cooling technology [11]. Therefore, as the using materials of the magnetic refrigeration technology, a lot of crystalline and amorphous materials with high MCE have been produced in recent years [12][13][14][15][16][17][18][19][20][21][22][23]. The basic demands of magnetocaloric materials (MCM) for magnetic cooling are the tuneable T C , high (-ΔS M ) and RC.…”

The magnetocaloric and magnetoresistance properties of amorphous Co-based (Co 0.402 Fe 0.201 Ni 0.067 B 0.227 Si 0.053 Nb 0.05 ) 100−x Cu x (x = 0, 0.5, 0.75 and 1) ribbons were investigated. Cu additions changed the crystallisation temperature (T x ) and the Curie temperature (T C ). The saturation magnetisation (M s ) and coercivity (H c ) for alloys were in the range of 65.51-38.49 emu/g and 1.99-6.84 A/m, respectively. Under an applied magnetic field change of 2.2 T, the (−ΔS M ) max for (Co 0.402 Fe 0.201 Ni 0.067 B 0.227 Si 0.053 Nb 0.05 ) 100−x Cu x with x = 0, 0.5, 0.75 and 1 are 0.77, 0.71, 0.89 and 0.67 Jkg −1 K −1 , respectively. The values of refrigeration capacity (RC) for the as-spun glassy alloys are comparable with those of previously studied Fe-based metallic glasses such as Fe 80 B 10 Zr 9 Cu 1 , (Fe 0.76 B 0.24 ) 96 Nb 4 and Fe 82 Ni 2 Zr 6 B 10 . In addition, the maximum magnetoresistance (MR) values for (Co 0.402 Fe 0.201 Ni 0.067 B 0.227 Si 0.053 Nb 0.05 ) 100−x Cu x with x = 0, 0.5, 0.75 and 1 are found to be 110, 38, 23 and 1% around the Curie temperatures under an applied magnetic field change of 1 T, respectively. With good RC, negligible hysteresis due to very low coercivity values and large magnetoresistance, these Co-based amorphous alloys can be used as the high temperature magnetic refrigerants and multifunctional applications working in the temperature range of 450-600 K.
