“…The static field was applied in the film plane and along the exchange-bias direction. As shown in [77], physically the exchange bias is an in-plane uni-directional interface anisotropy leading to pinning of the dynamic magnetisation at the interface of the two layers. The experiments demonstrated that when the applied field was coaligned with the exchange-bias field direction, the FMR spectra were of the type shown in the right-hand column of Fig.…”

“…Similarly, every time when the applied field is along the anisotropy axis, both dynamic magnetisation components will be pinned, just for the sheer reason of the uniaxial symmetry introduced by the uniaxial anisotropy. For instance, if an IP exchange-bias field is present at one of the film surfaces and the static field is applied in the direction of the exchange bias, both components of m will be pinned/anti-pinned, although the geometry is one of the IP FMR [77].…”

This article presents a comprehensive critical overview of fundamental and practical aspects of the modern stripline broadband ferromagnetic resonance (BFMR) spectroscopy largely employed for the characterisation of magnetic low-dimensional systems, such as thin ferro-and ferromagnetic, multiferroic and half-metallic films, multi-layers and nanostructures. These planar materials form the platform of the nascent fields of magnonics and spintronics. Experimental and theoretical results of research on these materials are summarised, along with systematic description of various phenomena associated with the peculiarities of the stripline BFMR, such as the geometry of stripline transducers, the orientation of the static magnetic field, the presence of microwave eddy currents, and the impacts of non-magnetic layers, interfaces and surfaces in the samples. Results from more than 240 articles, textbooks and technical reports are presented and many practical examples are discussed in detail. This review will be of interest to both general physical audience and specialists conducting research on various aspects of magnetisation dynamics and nanomagnetism.

“…[11][12][13][14][15][16][17][18] Standing spin waves have also been used to study exchange bias as an interface pinning effect. 19 In this work, we investigate primarily using FMR the magnetic properties of a Ni 0.8 Fe 0.2 /Fe 0.5 Mn 0.5 multilayer test structure. Structural and chemical analyses show layer thickness and interface roughness variations across the sample and we are able to correlate magnetic features with specific layers, including the influence of layer position within the stack.…”

We report the static and dynamic magnetic characteristics of a high-layer-number NiFe/FeMn multilayer test structure with potential applications in broadband absorber and filter devices. To allow fine control over the absorption linewidths and to understand the mechanisms governing the resonances in a tailored structure similar to that expected to be used in real world applications, the multilayer was intentionally designed to have layer thickness and interface roughness variations. Magnetometry measurements show that the sample has complex hysteresis loops with features consistent with single ferromagnetic film reversals. Characterisation by transmission electron microscopy allows us to correlate the magnetic properties with structural features, including the film widths and interface roughnesses. Analysis of resonance frequencies from broadband ferromagnetic resonance measurements as a function of field magnitude and orientation provide values of the local exchange bias, rotatable anisotropy, and uniaxial anisotropy fields for specific layers in the stack and explain the observed mode softening. The linewidths of the multilayer are adjustable around the bias field, approaching twice that seen at larger fields, allowing control over the bandwidth of devices formed from the structure.

Abstract:We develop an advanced analytical model for calculating the broadband stripline ferromagnetic resonance (FMR) response for metallic ferromagnetic films, taking into account the exchange interaction as well as the exchange boundary conditions at the film surface. This approach leads to simple analytical expressions in the Fourier space. As a result, a numerical code which implements inverse Fourier transform of these equations is very quick. This allows us to explore a wide space of parameters as numerical examples of application of this theory. In particular, we investigate the joint effect of microwave eddy current shielding and magnetisation pinning at the ferromagnetic film surfaces on the shape of the stripline FMR response of the film.
