Hexagonal RMnO 3 is a multiferroic compound with a giant spin-lattice coupling at an antiferromagnetic transition temperature [1]. Despite extensive studies over the past two decades, however, the origin and underlying microscopic mechanism of the strong spin-lattice coupling remain still very much elusive. In this study, we have tried to address this problem by measuring the thermal expansion and dielectric constant of doped single crystals

“…Moreover, T. Feng et al found that resonant tunneling can be realized in the MNG-vacuum-ENG structure [8]. In metamaterials, the propagation of electromagnetic waves has exhibited lots of promising applications, for instance, subwavelength lensing, electromagnetic cloaking, energy transferring and so on [3,8].…”

“…In this paper, we further derive analytically the conditions for transmission resonance of asymmetric three-layer medium in different combinations containing the ENG layer and the DPS layer. Kim et al proved theoretically that the surface mode plays an important role in complete tunneling that arises from balancing field enhancement and decay, and at least one interface supports the surface mode [3]. Therefore, the structure that we investigate contains at least one interface of ENG-DPS or DPS-ENG to provide the surface mode.…”

“…Kim and B. Lee investigated the conditions for and properties of the complete tunneling of light through a composite barrier made of impedance-mismatched metamaterial layers [6]. Then complete tunnelings of multiple layers and normally incident light through singly negative materials were also investigated [3,7]. Moreover, T. Feng et al found that resonant tunneling can be realized in the MNG-vacuum-ENG structure [8].…”

“…These extraordinary phenomena usually occur in a multi-layer structure containing epsilon-negative (ENG) or mu-negative (MNG) slabs. The origin of complete tunneling is explained as the balance between the enhancement and decay of the evanescent fields inside the layers [3]. A. Alù and N. Engheta discovered that, when passing through opaque media such as the ENG-MNG structure, electromagnetic waves can generate an extraordinary phenomenon-resonant tunneling (with total transmission * E-mail: naihuizhao@gmail.com and zero phase delay) [4].…”

Abstract:With the transfer-matrix method, conditions of extraordinary electromagnetic resonant tunneling through all combinations of three-layer nonmagnetic (µ = 1) media containing epsilon-negative (ENG) and doublepositive (DPS) slabs were explored. We show that abnormal phenomena can occur in the ENG-DPS-ENG structure, without any restriction on the permittivity of the DPS layer. Changes of transmittance as a function of frequency and incidence angle for a dispersive, lossy model are also calculated, and the results demonstrate the possibility of exhibition this counterintuitive tunneling phenomenon in the DPS-ENG-DPS structure within a wide range of incidence angles.PACS (

Manipulation of Magnetic Properties by Oxygen Vacancies in Multiferroic YMnO₃

Generating a single material with multiple ferroic properties has been the hotspot of research interest for decades. The existing studies mostly focus on the intrinsic properties of multiferroic materials, overlooking the importance of the widely distributed defects in the materials. Here, the strong influence of oxygen vacancies (V O) on the magnetic properties of YMnO3 is demonstrated. The first‐principles calculations reveal that the V O at axial positions can induce a nonzero net magnetization along the c‐axis. By structural characterization and magnetic measurement, this theoretically predicted ferromagnetic property is experimentally confirmed in the YMnO3 film grown on a c‐Al2O3 substrate. The large in‐plane compressive strain provided by the Al2O3 substrate allows to create the axial V O of YMnO3 film in this system. The ferroelectricity of YMnO3 is also preserved even under large in‐plane compressive strain. Therefore, the coexistence of the ferroelectric and ferromagnetic properties can be realized in the YMnO3 film, which is of practical interest for technological applications.
