Magnetic Ordering in CeZnGe
نویسندگان
چکیده
CeZnGe crystallizes with the hexagonal YPtAs-type structure, space group P63/mmc, a = 430.0(2), c = 1678.8(10) pm. A phase-pure sample was synthesized from the elements in a sealed tantalum crucible in a high-frequency furnace. Magnetic susceptibility measurements have revealed a trivalent cerium with an experimental magnetic moment of 2.67(1) μB/Ce atom. Ferromagnetic ordering sets in at TC = 4.6(2) K.

Investigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...

Coexistence of superconductivity and magnetic ordering or their mutually exclusive existence in solids is one of the fundamental problems of solid state physics. To determine the effect of Pr substitution for Gd on electrical and magnetic properties of RuGd1.5Ce0.5Sr2Cu2O10-δ (Ru-1222), Ru(Gd1.5-xPrx)Ce0.5Sr2Cu2O10-δ with x=0.0, 0.01, 0.03, 0.03 3 , 0.04, 0.05, 0.06, 0.1 have been prepared by...
متن کاملComparison of the effect of Si and Ge presence on phase formation process, the structural and magnetic properties of Co2FeX (X=Ge,Si) Heusler compounds
In this study, the Co2FeX (X=Ge, Si) Heusler compounds with 30 valence electrons, which are made by using mechanical alloying and arc melting methods were studied. The crystallization of samples was confirmed by XRD data in both manufacturing methods. The results showed that the presence of Si than Ge in the compound played a more effective role to creation a large scale atomic ordering, and th...
