We present the optimization of a new material structure used as transducer in a MagnetoOptical Surface Plasmon Resonance (MOSPR) biosensor. The MOSPR sensor is a modification of the standard Surface Plasmon Resonance (SPR) biosensor, which arises from the introduction of a ferromagnetic metal layer with Magneto-Optical (MO) activity together with the usual gold layer of SPR biosensors. Such com...

Abstract Structural, half-metallic, magneto-optic, and thermoelectric properties of CrTiZ (Z = As, P) half-Heusleres compounds are investigated based on density functional theory. These have mechanical stability in the ferromagnetic state with a high bulk modulus. They often half-metallic large integer magnetic moment very attractive spintronics, magneto-optics applications. The moments CrTiAs ...

We present the classical electromagnetic theory framework of reflection a light beam carrying orbital angular momentum (OAM) by magnetic structure with generic symmetry. Depending on magnetization symmetry, we find change in OAM content reflected due to magneto-optic interaction and an asymmetric far-field intensity profile. This leads three types helicoidal dichroism (MHD), observed when switc...

We studied magnetophotonic crystals (MPCs) with introduced magneticdefect layer sandwiched between magnetic and dielectric Bragg mirrors. Thesemagnetophotonic crystals have excellent capabilities to enhance reflection and Kerrrotation simultaneously. By adjusting spatial configuration such as repetition numbersof Bragg mirrors and thickness of magnetic defect layer, we a...

In this joint experimental and ab initio study, we focused on the influence of the chemical composition and martensite phase transition on the electronic, magnetic, optical, and magneto-optical properties of the ferromagnetic shape-memory Ni-Mn-Ga alloys. The polar magneto-optical Kerr effect (MOKE) spectra for the polycrystalline sample of the Ni-Mn-Ga alloy of Ni60Mn13Ga27 composition were me...

In this paper, we analyze the magnetoplasmonic MP features and sensing capabilities of Au/Fe/Au trilayer structures, as transducers of the magneto-optic surface plasmon resonance MOSPR biosensor. This biosensor, which can surpass the sensitivity of the standard SPR sensor, is based on a MP modulation technique generated by the simultaneous stimulation of the surface plasmon polaritons SPP and t...

MnBi thin films have been considered for short-wavelength rewritable optical recording media due to the very large magneto-optic Kerr rotation and perpendicular anisotropy (Ku) of the hexagonal magnetic low-temperature MnBi phase. However, coincident structural and magnetic transformations near the Curie temperature ~360 °C! result in poor thermal cycling behavior, preventing the application of...

The diagonal component ␧ xx and off-diagonal component ␧ xy of the complex dielectric tensor for the ferromagnetic compound NiMnSb are determined using ex situ spectroscopic ellipsometry and magneto-optic analysis over the spectral range from 0.7 to 6.2 eV. The effects of the overcoat on the raw data are removed by the analysis. First, the complex ␧ xx of thin-film NiMnSb were determined by ex ...
