Abstract

Structural, magnetic, magnetocaloric, electrical and magnetoresistance properties of an LaNaMnMoO powder sample have been investigated by X-ray diffraction (XRD), magnetic and electrical measurements. Our sample has been synthesized using the ceramic method. Rietveld refinements of the XRD patterns show that our sample is single phase and it crystallizes in the orthorhombic structure with Pnma space group. Magnetization versus temperature in a magnetic applied field of 0.05 T shows that our sample exhibits a paramagnetic-ferromagnetic transition with decreasing temperature. The Curie temperature is found to be 320 K. Arrott plots show that all our double-perovskite oxides exhibit a second-order magnetic phase transition. From the measured magnetization data of an LaNaMnMoO sample as a function of the magnetic applied field, the associated magnetic entropy change |-ΔSM| and the relative cooling power (RCP) have been determined. In the vicinity of , |-ΔSM| reached, in a magnetic applied field of 8 T, a maximum value of ∼4 J kg K. Our sample undergoes a large magnetocaloric effect at near-room temperature. Resistivity measurements reveal the presence of an insulating-metal transition at Tρ = 180 K. A magnetoresistance of 30% has been observed at room temperature for 6 T, significantly larger than that reported for the AFeMoO (A = Sr, Ba) double-perovskite system.

摘要

通过X射线衍射（XRD）、磁性和电学测量，对LaNaMnMoO粉末样品的结构、磁性、磁热、电学和磁阻特性进行了研究。我们的样品采用陶瓷法合成。XRD图谱的Rietveld精修表明，我们的样品为单相，结晶为具有Pnma空间群的正交结构。在0.05 T的外加磁场中，磁化强度与温度的关系表明，我们的样品随着温度降低呈现顺磁-铁磁转变。发现居里温度为320 K。Arrott图表明，我们所有的双钙钛矿氧化物都表现出二级磁相变。根据LaNaMnMoO样品作为外加磁场函数的测量磁化数据，确定了相关的磁熵变|-ΔSM|和相对制冷量（RCP）。在 附近，在8 T的外加磁场中，|-ΔSM|达到最大值约4 J kg K。我们的样品在近室温下经历了较大的磁热效应。电阻率测量揭示了在Tρ = 180 K时存在绝缘-金属转变。在室温下6 T时观察到30%的磁阻，明显大于AFeMoO（A = Sr，Ba）双钙钛矿体系报道的磁阻。
