A new magnetoelectric effect is predicted originating from the interlayer exchange coupling between two ferromagnetic layers separated by an ultrathin ferroelectric barrier. It is demonstrated that ferroelectric polarization switching driven by an external electric field leads to a sizable change in the interlayer exchange coupling. The effect occurs in asymmetric ferromagnet/ferroelectric/ferr...

The magnetic properties of a mixed spin-2 and spin5 2 Ising ferrimagnetic system on a layered honeycomb lattice are studied. In particular we investigate the effect of a single-ion anisotropy and an interlayer interaction on the compensation phenomenon, in order to clarify the characteristic features observed in a series of molecular-based magnets AFeFe (C2O4)3@A5N(n-CnH2n11)4 , n53 –5]. We car...

The contribution of subnanometer pores in carbon electrodes to the charge-storage mechanism in supercapacitors has been the subject of intense debate for over a decade. Here, we provide a model system based on graphene oxide, which employs interlayer constrictions as a model for pore sizes that can be both controllably tuned and studied in situ during supercapacitor device use. Correlating elec...

Monolayer two-dimensional (2D) crystals exhibit a host of intriguing properties, but the most exciting applications may come from stacking them into multilayer structures. Interlayer and interfacial shear interactions could play a crucial role in the performance and reliability of these applications, but little is known about the key parameters controlling shear deformation across the layers an...

The ability to control the stacking structure in layered materials could provide an exciting approach to tuning their optical and electronic properties. Because of the lower symmetry of each constituent monolayer, hexagonal boron nitride (h-BN) allows more structural variations in multiple layers than graphene; however, the structure-property relationships in this system remain largely unexplor...

The self-assembly of low molecular weight gelators confined within the nano-scale interlayer space of organo-montmorillonite is likely to be different from that under normal conditions (bulk space). Four kinds of gelators, 1-methyl-2,4-bis(N'-n-octadecylureido) benzene (MBB18), 1-methyl-2,4-bis(N'-n-dodecylureido)benzene (MBB12), bis(4'-stearamido phenyl) methane (BSM18) and bis(4'-octanamido p...

Due to the intrinsic connection between the mechanical properties of carbon nanotubes and their long-ranged interactions, an accurate description for both covalent and van der Waals forces is desired in nanomechanical studies. A tight-binding treatment offers an accurate description for the covalent bonding but fails to account for the long-ranged attractions and for the energy variations of gr...

A Ginzburg-Landau–like functional is proposed reproducing the main low-energy features of various possible high-Tc superconducting mechanisms involving energy savings due to interlayer interactions. The functional may be used to relate these savings to experimental quantities. Two examples are given, involving the mean-field specific heat jump at Tc and the superconducting fluctuations above Tc...

Significant enhancement of the interlayer coupling strength has been achieved by depositing Co nanolayers on both sides of the Ru layer in a conventional CoCrPt/Ru/CoCrPt antiferromagnetic interlayer exchange coupling structure. The interlayer coupling increases nearly linearly from 0.13 to 0.8 erg/cm and then levels off with an increase in Co thickness. Substrate bias was found to be very harm...
