Double-percolation and magnetoresistance effects in ferromagnet-superconductor nanoparticle composites
Xiangdong Liu, Raghava P. Panguluri, Daniel P. Shoemaker +2
We investigate transport and magnetotransport properties of binary networks composed of superconducting (MgB2) and ferromagnetic (CrO2 or LSMO) nanoparticles. While for the LSMO/Mg…
Stability analysis of twist grain boundaries in lamellar phases of block copolymers
Xusheng Zhang, Zhi-Feng Huang, Jorge Viñals
Twist grain boundaries are widely observed in lamellar phases of block copolymers. A mesoscopic model of the copolymer is used to obtain stationary configurations that include a tw…
Grain boundary dynamics in stripe phases of non potential systems
Zhi-Feng Huang, Jorge Vinals
We describe numerical solutions of two non potential models of pattern formation in nonequilibrium systems to address the motion and decay of grain boundaries separating domains of…
Stability of parallel/perpendicular domain boundaries in lamellar block copolymers under oscillatory shear
Zhi-Feng Huang, Jorge Vinals
We introduce a model constitutive law for the dissipative stress tensor of lamellar phases to account for low frequency and long wavelength flows. Given the uniaxial symmetry of th…
Orientation selection in lamellar phases by oscillatory shears
Zhi-Feng Huang, Jorge Vinals
In order to address the selection mechanism that is responsible for the unique lamellar orientation observed in block copolymers under oscillatory shears, we use a constitutive law…
Tilt grain boundary instabilities in three dimensional lamellar patterns
Zhi-Feng Huang, Jorge Vinals
We identify a finite wavenumber instability of a 90 tilt grain boundary in three dimensional lamellar phases which is absent in two dimensional configurations. Both a sta…
