论文摘要
为了优化Hob $ _ {2} $的巨型磁磁性能，我们合成和磁通量表征HO $ _ {1-x} $ gd $ _ {x} $ _ {x} $ b $ _ {2} $（0.1 $ \ leq $ x $ x $ x $ \ leq $ 0.4）我们发现，GD在石化和随机进入HO位点，导致Vegard型结构变化。球形S $^{7/2} $ gd $^{3+} $矩的添加促使Curie温度增强，磁熵变化的峰值降低，同时仍然相对较高，并且磁熵变化变化曲线的扩展。总体影响是相对较高的制冷剂能力和相对冷却能力，并且将热工作范围扩展到更高的温度。因此，选举ho $ _ {1-x} $ gd $ _ {x} $ b $ _ {2} $（作为低温制冷应用的潜在候选者。
Intending to optimize the giant magnetocaloric properties of HoB$_{2}$, we synthesized and magnetocalorically characterized Ho$_{1-x}$Gd$_{x}$B$_{2}$(0.1 $\leq$ x $\leq$ 0.4) alloys. We found out that Gd enters stoichiometrically and randomly into the Ho site, leading to a Vegard-type structural change. The addition of spherical S$^{7/2}$ Gd$^{3+}$ moments prompts an enhancement in Curie temperature, a reduction in peak value of the magnetic entropy change while still being relatively high, and a broadening of the magnetic entropy change curves. The overall influence is a relatively high refrigerant capacity and relative cooling power, and an extension of the thermal working range to higher temperatures; thus, electing Ho$_{1-x}$Gd$_{x}$B$_{2}$(as potential candidates for cryogenic refrigeration applications.
