论文摘要
$ _ {5} $ pt $ _2 $ in $ _4 $（re = gd-tm）稀土化合物已通过X射线衍射（XRD）以及DC和AC磁力测量测量进行了研究。该化合物在lu $ _ {5} $ ni $ _2 $ in $ _4 $ -Type（\ textit {pbam}太空集团，编号〜55）的lu $ _ {5} $ ni $ _2 $的正交晶体结构中结晶。随着温度的降低，金属间经历了从para-/ferri-（re〜 = 〜gd，tb，ho，er）或抗磁磁状态（re〜 = 〜tm）的过渡。如果$ _ {5} $ pt $ _2 $ in $ _4 $，则通过在有限温度范围内的中间反铁磁序来达到铁磁状态。磁性排序的临界温度范围为4.1〜K（RE〜 = 〜TM）至108〜K（RE〜 = 〜TB）。对于大多数研究的化合物，在各自的磁有序临界温度下方发现了一系列额外的磁过渡。磁矩仅在稀土原子上发现，而其余的PT和原子的矩不存在或太小，无法在伴随着坚固的稀土矩时被检测到。 RE $ _ {5} $ t $ _2 $ in $ _4 $（re〜 = 〜gd-tm）的磁化（MCE）性能相当不错，尤其是在考虑到re = ho和er的化合物时。最大磁熵更改（$-ΔS_M^{max} $）到达11.8（re〜 = 〜HO）或11.4〜J $ \ cdot $ kg $^{ - 1} \ cdot $ k $^{ - 1} $（re〜 = 〜ER）在磁性通量密度变化0-9〜T下。在相同的条件下，相对冷却能力（RCP）和制冷剂容量（RC）等于607和495〜J $ \ cdot $ kg $^{ - 1} $（re〜 = 〜HO）或434和434和341〜J $ \ cdot $ kg $ kg $ kg $^{ - 1} $（re〜 =〜= 〜ER）。
The RE$_{5}$Pt$_2$In$_4$ (RE = Gd-Tm) rare earth compounds have been investigated by means of X-ray diffraction (XRD) as well as by DC and AC magnetometric measurements. The compounds crystallize in an orthorhombic crystal structure of the Lu$_{5}$Ni$_2$In$_4$-type (\textit{Pbam} space group, No.~55). With decreasing temperature the intermetallics undergo a transition from para- to ferro-/ferri- (RE~=~Gd, Tb, Ho, Er) or antiferromagnetic state (RE~=~Tm). In case of Dy$_{5}$Pt$_2$In$_4$, the ferromagnetic state is reached through an intermediate antiferromagnetic order present in a limited temperature range. The critical temperatures of magnetic ordering range from 4.1~K (RE~=~Tm) up to 108~K (RE~=~Tb). For the majority of investigated compounds, a cascade of additional magnetic transitions is found below the respective critical temperatures of magnetic ordering. The magnetic moments are found solely on the rare earth atoms, while the moments of the remaining Pt and In atoms are absent or are too small to be detected while accompanied by the strong rare earth's moments. The magnetocaloric (MCE) performance of RE$_{5}$T$_2$In$_4$ (RE~=~Gd-Tm) is found quite good, especially while taking into account the compounds with RE = Ho and Er. Maximum magnetic entropy change ($-ΔS_M^{max}$) reaches 11.8 (RE~=~Ho) or 11.4~J$\cdot$kg$^{-1}\cdot$K$^{-1}$ (RE~=~Er) under magnetic flux density change of 0-9~T. Under the same conditions, the relative cooling power (RCP) and refrigerant capacity (RC) equal 607 and 495~J$\cdot$kg$^{-1}$ (RE~=~Ho) or 434 and 341~J$\cdot$kg$^{-1}$ (RE~=~Er).
