Paramagnetic spin correlations inCaFe2As2single crystals

Paramagnetic spin pumping.

We have demonstrated spin pumping from a paramagnetic state of an insulator La2NiMnO6 into a Pt film. Single-crystalline films of La2NiMnO6 which exhibit a ferromagnetic order at TC≈270  K were grown by pulsed laser deposition. The inverse spin Hall voltage induced by spin-current injection has been observed in the Pt layer not only in the ferromagnetic phase of La2NiMnO6, but also in a wide te...

Spin Fluctuations in Paramagnetic Nickel

The temperature dependence of the cross section for inelastic magnetic scattering of neutrons in constant-q scan has been studied using results of renormalization group theory. The temperature behaviour of the peak in the-cross section and its width are in good agreement with the results of computation of the cross section for paramagnetic Ni using acurae energy bands. The spin fluctuations abo...

Spin correlations in the paramagnetic phase and ring exchange in La2CuO4.

Spin correlations in the paramagnetic phase of La(2)CuO(4) have been studied using polarized neutron scattering, with two important results. First, the temperature dependence of the characteristic energy scale of the fluctuations and the amplitude of the neutron structure factor are shown to be in quantitative agreement with the predictions of the quantum nonlinear sigma model. Second, a compar...
