Elastic properties and magnetic phase diagrams of dense Kondo compound Ce0.75La0.25B6

We have investigated the elastic properties of the cubic dense Kondo compound Ce0.75La0.25B6 by means of ultrasonic measurements. We have obtained magnetic fields vs. temperatures (H−T ) phase diagrams under magnetic fields along the crystallographic [001], [110] and [111] axes. An ordered phase IV showing the elastic softening of c44 locates in low temperature region between 1.6 K and 1.1 K be...

Magnetic phase diagrams of the Kagomé staircase compound Co3V2O8

At zero magnetic field, a series of five phase transitions occur in Co3V2O8. The Néel temperature, TN=11.4 K, is followed by four additional phase changes at T1=8.9 K, T2=7.0 K, T3=6.9 K, and T4=6.2 K. The different phases are distinguished by the commensurability of the b-component of its spin density wave vector. We investigate the stability of these various phases under magnetic fields throu...

Unusual ground-state properties of the Kondo-lattice compound Yb2Ir3Ge5

We report sample preparation, structure, electrical resistivity, magnetic susceptibility and heat capacity studies of a new compound Yb2Ir3Ge5. We find that this compound crystallizes in an orthorhombic structure with a space group PMMN unlike the compound Ce2Ir3Ge5 which crystallizes in the tetragonal IBAM (U2Co3Si5 type) structure. Our resistivity measurements indicate that the compound Yb2Ir...

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...
