Local spin moment distribution in antiferromagnetic molecular rings probed by NMR.
The NMR spectra of 19F and 53Cr have been obtained at low temperatures in a heterometallic substituted antiferromagnetic (AF) ring Cr7Cd with an S=3/2 ground state and compared with the spectra in a homometallic Cr8 AF ring with an S=0 ground state. From the analysis of the spectra one can derive directly model independent values of the staggered nonuniform distribution of the local moment in t...
متن کاملApproximation of Second-Order Moment Processes from Local Averages
In the literature, very few researchers considered approximating Brownian motion using Bernstein polynomials. Kowalski 1 is the first one who uses this method. In fact, if we restrict Brownian motion on 0, 1 , it is a real process with finite second order moment. In this paper, we will approximate all of the complex second order moment processes on a, b by Bernstein polynomials and other classi...
متن کاملBa(1-x)K(x)Mn2As2: an antiferromagnetic local-moment metal.
The compound BaMn2As2 with the tetragonal ThCr2Si2 structure is a local-moment antiferromagnetic insulator with a Néel temperature T(N)=625 K and a large ordered moment μ=3.9μ(B)/Mn. We demonstrate that this compound can be driven metallic by partial substitution of Ba by K while retaining the same crystal and antiferromagnetic structures together with nearly the same high T(N) and large μ. Ba(...
متن کاملNon Collinear Moment in Single Domain Antiferromagnetic Manganese-copper
Diffuse neutron scattering measurements incorporating polarisation analysis have been made on a single domain single crystal of MnCu 90 at. % Mn at 5 K. The atoms are strongly clustered and the long range part of the magnetic defect is transverse to the antiferromagnetic direction. The face centred tetragonal form of manganese which can be stabilised at room temperature by the addition of small...
متن کاملAntiferromagnetic order in the FFLO state
We investigate the antiferromagnetic (AF) order in the d-wave superconducting (SC) state at high magnetic fields. A two-dimensional model with on-site repulsion U , intersite attractive interaction V and antiferromagnetic exchange interaction J is solved using the mean field theory. For finite values of U and J , a first order transition occurs from the normal state to the FFLO state, while the...
