Pressure-induced Suppression of the Antiferromagnetic Transition in YbNi3Al9 Single Crystal
نویسندگان
چکیده
We have measured the electrical resistivity ρ(T ) of heavy fermion antiferromagnet YbNi3Al9 under hydrostatic pressure up to 8 GPa. We found that the antiferromagnetic ordering temperature TN is suppressed with increasing pressure, whereas the localized character of the trivalent Yb state becomes stronger inferred from the reduction of the Kondo scattering. We will discuss the possible origin of the suppression of TN under pressure.

Neutron scattering is proved to be a vital probe in unveiling the magnetic properties of high temperature superconductors (HTSC). Detailed information about the energy and momentum dependence of the magnetic dynamics of HTSC have been obtained directly by this technique. Over the past decade by improving the crystal growth methods, large and high quality single crystals of HTSC, which are ess...
متن کاملPressure-induced phase transition in PbSc0.5Ta0.5O3 as a model Pb-based perovksite-type relaxor ferroelectric.
We report pressure-induced structural changes in PbSc(0.5)Ta(0.5)O3 studied by single-crystal x-ray diffraction and Raman scattering. The appearance of a soft mode, a change in the volume compressibility, broadening of the diffraction peaks, and suppression of the x-ray diffuse scattering show that a phase transition occurs near pc approximately 1.9 GPa. The critical pressure is associated with...
متن کاملMagnetic, transport, and thermodynamic properties of CaMn2O4 single crystals
Physical properties including magnetic susceptibility, room-temperature electrical resistivity, thermal conductivity, heat capacity, and thermal expansion are reported for high quality single-crystal samples of marokite CaMn2O4. We determined that CaMn2O4 is highly electrically insulating and exhibits long-range antiferromagnetic order below TN=217.5 0.6 K with easy axis along a. Anisotropic th...
متن کاملInterface-induced superconductivity at ∼25 K at ambient pressure in undoped CaFe2As2 single crystals.
Superconductivity has been reversibly induced/suppressed in undoped CaFe2As2 (Ca122) single crystals through proper thermal treatments, with Tc at ∼25 K at ambient pressure and up to 30 K at 1.7 GPa. We found that Ca122 can be stabilized in two distinct tetragonal (T) phases at room temperature and ambient pressure: PI with a nonmagnetic collapsed tetragonal (cT) phase at low temperature and PI...
متن کاملField-induced suppression of the heavy-fermion state in YbRh2Si2.
We report dc-magnetization measurements on YbRh2Si2 at temperatures down to 0.04 K, magnetic fields B< or =11.5 T, and under hydrostatic pressure P< or =1.3 GPa. At ambient pressure a kink at B* =9.9 T indicates a new type of field-induced transition from an itinerant to a localized 4f state. This transition is different from the metamagnetic transition observed in other heavy-fermion compounds...
