Effect of Nd and Rh substitution on the spin dynamics of Kondo insulator CeFe2Al10
P. A. Alekseev, J. -M. Mignot, D. T. Adroja +7
The dynamic magnetic properties of the Kondo-insulator state in CeFe2Al10 (spin gap, resonance mode) have been investigated using polarized neutrons on a single crystal of pure CeF…
Temperature-Dependent Cycloidal Magnetic Structure in GdRuAl Studied by Resonant X-ray Diffraction
Takeshi Matsumura, Takayoshi Yamamoto, Hiroshi Tanida +1
We have performed resonant X-ray diffraction experiments on the antiferromagnet GdRuAl and have clarified that the magnetic structure in the ordered state is cycloidal…
Kondo effect in CeX (X=S, Se, Te) studied by electrical resistivity under high pressure
Y. Hayashi, S. Takai, T. Matsumura +5
We have measured the electrical resistivity of cerium monochalcogenices, CeS, CeSe, and CeTe, under high pressures up to 8 GPa. Pressure dependences of the antiferromagnetic orderi…
Incommensurate-Commensurate Magnetic Phase Transition in SmRuAl
S. Takai, T. Matsumura, H. Tanida +1
Magnetic properties of single crystalline SmRuAl have been investigated by electrical resistivity, magnetic susceptibility, and specific heat. We have confirmed the su…
Relation between - hybridization and magnetic ordering in CeRuAl: An optical conductivity study of Ce(RuRh)Al ()
Shin-ichi Kimura, Hiroshi Tanida, Masafumi Sera +5
A Kondo semiconductor CeRuAl with an orthorhombic crystal structure shows an unusual antiferromagnetic ordering at rather high temperature of 27.3 K, which is lowe…
Dispersive magnetic resonance mode in the Kondo semiconductor CeFe2Al10
Jean-Michel Mignot, Pavel A. Alekseev, Julien Robert +7
The CeT2Al10 family of orthorhombic compounds exhibits a very peculiar evolution from a Kondo-insulator (T: Fe) to an unconventional long-range magnetic order (T: Ru, Os). Inelasti…
