Abstract

The crystal structure of MnRuxRh1-xAs system belongs to the hexagonal Fe2P-type structure (SG: P 6 2m). Mn atoms locate at pyramidal (3g) sites, Ru and Rh atoms occupy tetrahedral (3f) sites and As atoms occupy 1b and 2c positions. Systematic XRD data collected in the 80 - 550 K temperature range and crystal structure refinements were performed for 0.05 < x < 1. From the thermal behavior of both the cell parameters and the atomic positions, a global analysis of the magneto-elastic characteristics was made. In this report we present the magnetocaloric characteristics (MCE), addressed to the Mn magnetic ordering. Both conventional (0.8

MnRuxRh1-x As体系的磁弹性性能:晶体、电子结构和磁热效应分析

MnRuxRh1-xAs体系的晶体结构属于六方fe2p型结构(SG: p62m)。Mn原子位于锥体(3g)位置，Ru和Rh原子位于四面体(3f)位置，As原子位于1b和2c位置。在80 ~ 550 K温度范围内采集系统XRD数据，并在0.05 < x < 1的条件下对晶体结构进行细化。从电池参数和原子位置的热行为出发，对其磁弹性特性进行了全局分析。在这个报告中，我们提出了磁热特性(MCE)，解决了锰的磁有序。指出了常规MCE (0.8
