Abstract We present a computer simulation and theoretical study of composite multiferroics acting as magnetic field detectors. Our set-up consists of a layer of piezoelectric sandwiched between two magnetostrictive layers. When magnetic field is appl

The magneto-electric effect is very much enhanced in multiferroic composite materials due to the long range ferroic ordering and stress mediated magneto-electric coupling. This opens the possibility for applications of multiferroic composites to adva

The existing magnetic recording read head technologies use one of the well-known magneto-resistance effects (i.e. anisotropic magneto-resistance, giant magneto-resistance or tunnelling magneto-resistance (TMR)) to read back the data from the magnetic

The Zhang–Levy–Granovskii (Z–L–G) model of the magnetorefractive effect (MRE) in granular films and the Jacquet–Valet (J–V) model, originally developed for magnetic multilayers, are compared and their common origin demonstrated. Simulatio

Difficulties in controlling the grain size and size distribution in polycrystalline thin films are a major obstacle in achieving efficient performance of thin film devices. In this paper we describe a sputtering technology that allows the control of

Electrical magnetoresistance measurements of spin dependent materials or devices are very difficult without surface damaging or sample contamination, especially for thin-film giant magnetoresistance (GMR) multilayers. Moreover, the in situ determinat

A practical approach for in-plane angular spin distributions in layered systems, as obtained by Mossbauer spectroscopy, is discussed. The line intensity ratio R23 of a Mossbauer pattern is expressed versus particular distribution parameters in unidir

A comparative experimental study, regarding the effect of the interactions on the anisotropy field, is discussed in this paper. Two different sets of magnetic samples have been analysed using rotational hysteresis and standard remanence measurements.
