Enhancement of giant refrigerant capacity in Ho1-xGdxB2 alloys (0.1 ≤ x ≤ 0.4)
Journal of Alloys and Compounds(2021)
摘要
•The influence of Gd substitution was investigated in the magnetic and magnetocaloric properties of HoB2.•The introduction of Gd leads to higher TC values up to 30 K.•The refrigerant capacity is enhanced up to 6.07 J cm−3 for a field change of 5 T.•The addition of Gd also leads to broader “table-like” entropy curves.
