Capillary force mechanisms have the advantages of providing the motive force to move groups of particles to locations of interest while holding them in place, offering delicateness, and obviating the use external energy sources. We report a capillary force method that permits particles to remain hydrated, while assembled and harvested in batches using a single setup, furthermore assembly of different sizes/types is possible. The physics behind the process is described and the technique demonstrated with the formation of an ensemble of 6 μm particles.

    Electron spin dynamics in n-type c-oriented wurtzite GaN epilayers is studied by time-resolved Kerr-rotation measurements at T=80 K. The electron spin lifetime shows a sudden increase if an external magnetic field is applied in the sample plane. This enhancement is explained by anisotropic...

    We study hot-electron capture on resonant N-impurities in the dilute nitride Ga(AsN) alloy under high magnetic fields up to 23 T. We show that when the ratio of electric and magnetic fields reaches a critical value, the trajectory of conduction electrons becomes fully localized in real space;...

    The anomalous magnetoresistance (MR) of the interference origin was first observed in the weakly doped nongenerated n-Ge:Sb and p-Ge:Ga. Early proposed for the MR detection, the electron spin resonance technique was used for this investigation. It was found that the anomalous MR was observed in...

    High-field electron paramagnetic resonance (EPR) is used to investigate two magnetically concentrated II1-xMnxVI alloys, Cd1-xMnxSe and Cd1-xMnxSe, for x>0.15. Earlier EPR studies carried out between 9.0 and 35 GHz had shown that the EPR linewidths in II1-xMnxVI alloys are determined by...

    It is shown that unpolarized paramagnetic centers can implement the spin filtration of unpolarized conduction electrons in semiconductors. This ability of paramagnetic centers is caused by the difference in the spin evolution of the states of electron-paramagnetic-center pairs and by the spin...

    The electron spin resonance is studied for noncollinear low-dimensional antiferromagnets RbMnBr[sub 3] and RbFe(MoO[sub 4])[sub 2] in a wide range of frequencies and fields. Both compounds have incommensurate spin structures appearing due to a low-symmetry distortion of an ideal hexagonal...

    The evolution of electron temperature in a low pressure magnetized capacitive discharge was investigated under the collisionless electron heating regime. The results showed that while the electron temperature increases monotonously with the magnetic field in previous study [Turner et al., Phys....

    Magnetodielectric coupling effects of single phase multiferroic Pb(Fe0.5Nb0.5)O3 ceramics have been studied using standard ferroelectric measurements and electron paramagnetic resonance (EPR). Changes in the electrical polarization behavior were observed in the paramagnetic to weakly magnetized...

    The temperature dependence of the ESR linewidth in La1 − x Ca x MnO3 single crystals with various dopant concentrations ( x = 0.18, 0.2, 0.22, 0.25, and 0.3) has been studied. An abrupt decrease in the ESR linewidth has been observed in the samples with a dopant concentration of x = 0.18...
