Anisotropic electromagnetic in-plane response of La1:96Sr0:04CuO4

چکیده
We report on the anisotropy of the in-plane electronic conductivity examined in the weakly doped phase of the highTc system La2 xSrxCuO4 with infrared spectroscopy. Evidence for spin stripes in these materials is well documented. We find anisotropy of the electronic response within the CuO2 planes with an enhancement of the conductivity by 50% parallel to the stripe direction in the limit T ;x ! 0. These results uncover a complex electronic behavior due to formation of charge stripes that is beyond an idealized picture of strictly one-dimensional charge channels. 2003 Elsevier Science B.V.

Analysis of Plane Waves in Anisotropic Magneto-Piezothermoelastic Diffusive Body with Fractional Order Derivative
In this paper the propagation of harmonic plane waves in a homogeneous anisotropic magneto-piezothermoelastic diffusive body with fractional order derivative is studied. The governing equations for a homogeneous transversely isotropic body in the context of the theory of thermoelasticity with diffusion given by Sherief et al. [1] are considered as a special case. It is found that three types of...
متن کاملSpin, Orbital, and Spin-Orbital Polarons in Transition Metal Oxides
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La2CuO4, (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO3, and (iii) spin-orbital polaron when a hole is added to the AF and AO ordered plane in LaVO3. Comparison of the dis...
متن کاملBending-Unbending Analysis of Anisotropic Sheet under Plane Strain Condition
The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...
متن کاملEffect of Stress Triaxiality on Yielding of Anisotropic Materials under Plane Stress Condition
The triaxiality of the stress state is known to greatly influence the amount of plastic strain which a material may undergo before ductile failure occurs. It is defined as the ratio of hydrostatic pressure, or mean stress, to the von Mises equivalent stress. This paper discusses the effects of stress triaxiality on yielding behavior of anisotropic materials. Hill-von Mises’s criteria for anisot...
