0 D ec 1 99 3 Theory of Coexisting Transverse Spin Freezing and Long - Ranged Antiferromagnetic Order in Lightly Doped La 2 − x Sr x CuO

چکیده
We provide an explanation of the spin–freezing transition recently observed by Chou et al. for x < ∼ .02. We propose that topological excitations of the 2D Heisenberg quantum antiferromagnet having non–coplanar transverse components have a pair–interaction energy that qualitatively and quantitatively agrees with the observed values of spin–freezing temperature as a function of doping.

Slow antiferromagnetic dynamics in the low temperature tetragonal phase of La 2−x Sr x CuO 4 as revealed by ESR of Gd spin probes Abstract Measuring the ESR of Gd spin probes we have studied the magnetic properties of the copper oxide planes in the low temperature tetragonal (LTT) phase of Eu doped La 2−x Sr x CuO 4. The data give evidence that at particular levels of Sr and Eu doping the frequ...
متن کاملCorrelations versus Superfluid Density in La 2 − x Sr x CuO
We have performed muon spin relaxation and low field ac-susceptibility measurements in a series of high quality samples of La 2−x Sr x CuO 4 (x = 0.08 − 0.24) as a function of temperature. Superconductivity is found to co-exist with low temperature spin glass order up to the optimally doped region where the normal state pseudogap also closes. The systematic depletion of the superfluid density w...

We present a combined magnetic neutron scattering and muon spin rotation study of the nature of the magnetic and superconducting phases in electronically phase separated La(2-x)Sr(x)CuO(4+y), x=0.04, 0.065, 0.09. For all samples, we find long-range modulated magnetic order below T(N) is approximately equal to Tc=39 K. In sharp contrast to oxygen-stoichiometric La(2-x)Sr(x)CuO(4), we find that t...
متن کاملMean-field pairing theory for the charge-stripe phase of high-temperature cuprate superconductors.
Striped high-T(c) superconductors such as La(2-y-x)Nd(y)Sr(x)CuO(4) and La(2-x)Ba(x)CuO(4) near x = 1/8 show a fascinating competition between spin and charge order and superconductivity. A theory for these systems therefore has to capture both the spin correlations of an antiferromagnet and the pair correlations of a superconductor. For this purpose we present here an effective Hartree-Fock th...

We examine the low–temperature magnetic properties of moderately doped La2−xSrxCuO4, paying particular attention to the spin–glass phase and the commensurate–incommensurate transition as they are affected by Sr impurity disorder. A model of the carriers, believed to be appropriate at low temperatures, is employed in the CuO2 planes that accounts for both the strong coupling of the hole’s motion...
