The Doniach diagram and hydrogenation of the ternary compounds CePdIn and CePdSn

摘要: The process of hydrogenation the antiferromagnetic compounds CePdIn and CePdSn has been studied. Investigation new hydrides CePdInH CePdSnH by means x-ray powder diffraction reveals that they adopt same crystal symmetry as original intermetallic but unit cell volume increases during hydrogenation. Magnetization, electrical resistivity, thermoelectric power 119Sn Mossbauer spectroscopy measurements reveal order antiferromagnetically below TN = 3.0(2) 5.0(2) K respectively. Moreover, physical properties are less influenced Kondo effect. changes Neel temperature induced H insertion explained on basis Doniach's diagram considering competition between Ruderman–Kittel–Kasuya–Yosida interactions.
