Antiferromagnetic spin fluctuations in CeRhSn
نویسندگان
چکیده
We have carried out Sn nuclear magnetic resonance (NMR) measurements on the quasi-Kagomé compound CeRhSn. We found that Sn Knight shift sKd is highly anisotropic and shows Curie-Weiss type temperature sTd dependence above 25 K. In this T range, the NMR relaxation rate shows s1/T1d~ÎT and is enhanced by magnetic fluctuations. At low T’s, K stays constant and the enhanced Korringa relation of sT1TKd=const is observed, differently from the non-Fermi-liquid behavior observed for bulk measurements. The present NMR results suggest that antiferromagnetic spin fluctuations exist in CeRhSn.

In this paper a simple model calculation of spin wave is given for the ferromagtic layer in ultra thin ferromagnetic/antiferromagnetic bilayer. In this model the magnetic layer is assumed as an isolated layer but the effect of antiferromagnetic layer on ferromagnetic layer and unidirectional anisotropy, is given in the effective field applied on each spin. The thin layer is assumed as two-dim...
متن کاملMagnetic correlations and quantum criticality in the insulating antiferromagnetic, insulating spin liquid, renormalized Fermi liquid, and metallic antiferromagnetic phases of the Mott system V2O3
Magnetic correlations in all four phases of pure and doped vanadium sesquioxide (V2O3) have been examined by magnetic thermal-neutron scattering. Specifically, we have studied the antiferromagnetic and paramagnetic phases of metallic V22yO3 , the antiferromagnetic insulating and paramagnetic metallic phases of stoichiometric V2O3 , and the antiferromagnetic and paramagnetic phases of insulating...

Magnetic correlations in all four phases of pure and doped vanadium sesquioxide (V2O3) have been examined by magnetic thermal neutron scattering. Specifically we have studied the antiferromagnetic and paramagnetic phases of metallic V2−yO3, the antiferromagnetic insulating and paramagnetic metallic phases of stoichiometric V2O3, and the antiferromagnetic and paramagnetic phases of insulating V1...

Motivated by recent experiments that detects Dzyaloshinskii-Moriya (DM) interaction in , we study the effects of DM interaction on magnetic orders of J1-J2 antiferromagnetic Heisenberg model. First, we find the classical phase diagram of the model using Luttinger-Tisza approximation. In this approximation, the classical phase diagram has two phases. For , the model has canted Neel and DM intera...
متن کاملAn itinerant antiferromagnetic metal without magnetic constituents
The origin of magnetism in metals has been traditionally discussed in two diametrically opposite limits: itinerant and local moments. Surprisingly, there are very few known examples of materials that are close to the itinerant limit, and their properties are not universally understood. In the case of the two such examples discovered several decades ago, the itinerant ferromagnets ZrZn2 and Sc3I...
