Crystal Structure and Magnetic Properties of La_0.8R_0.2(Fe_0.88Si_0.12)₁₃ (R = Sm and Tb) Compounds

Magnetic-Properties of RSr2NbCu2O8; R = Nd, and Tb Compounds Prepared under Extreme Conditions

The niobio-cuprates with starting composition, RSr2Nb0.9Cu2.1O7.9; R = Nd, and Tb have been prepared under extreme synthesis conditions and characterized by powder X-ray diffraction technique and their magnetic properties were investigated briefly in this article. The present high-pressure synthesized NdSr2Nb0.9Cu2.1O7.9 (Nd/1212Nb) compound has been compared briefly with the reported ambient p...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

MAGNETIC PROPERTIES OF THE AuCu3-TYPE Sm-COMPOUNDS

Resistivity, susceptibility, specific heat a d magnetization measurements on single crystals SmPb3, SmPds and SmT13 are performed. The phase transition of the antiferromagnet, SmPb3, is of first order at 5.1 K. SmPda shows an antiferromagnetic ordering at 1.36 K. SmT13 behaves as a ferromagnet with T, =8.6 K. The ground states of sm3+ (J= 512) ions in these Sm-compounds are r s quartets. Recent...
