“…Therefore, if the magnetizations become parallel before becoming aligned with the applied magnetic field, the magnetoresistance and magnetization will present different saturation fields. A similar result has been observed in Fe/Cr/Fe [110] trilayers ().…”

“…In particular, when the bilinear and biquadratic energies are comparable, our results show that the magnetizations of the films tend to align prior to saturation along the direction of the applied magnetic field. This effect has also been observed in [110] trilayers [8] and is attributable to the superposition of the cubic and uniaxial anisotropies when the bilinear and biquadratic energies are comparable.…”

“…Important subsequent findings include oscillations (from ferromagnetic to antiferromagnetic) in the interlayer exchange coupling as a function of the Cr layer thickness () and the experimental observation of biquadratic exchange coupling (). Recent publications have focused on developing an understanding of the static properties of quasiperiodic magnetic multilayers coupled via bilinear and biquadratic exchange fields and the effects of magneto‐crystalline anisotropies (). For example, new features of the static and dynamic magnetic properties associated with the Fibonacci quasiperiodicity in multilayers grown in the [100] and [110] directions, including the discovery of an anomalous magnetoresistance, have very recently presented new possibilities for information storage technologies and applications in logical devices .…”

We present a theoretical study about the influence of magneto‐crystalline anisotropies on the static and dynamic magnetic properties of trilayers coupled via bilinear and biquadratic exchange fields for situations in which the systems are grown in unusual [hkl] low‐symmetry directions. We apply a realistic phenomenological model, with a total free magnetic energy that includes Zeeman interaction and magneto‐crystalline anisotropies as well as exchange energy terms. We consider parameters from the literature to illustrate our results for Fe/Cr/Fe systems. In particular, a total of six different magnetic scenarios for the [211] and [321] low‐symmetry growth orientations and three sets of exchange fields were analyzed, and the associated magnetization, magnetoresistance, and spin‐wave frequencies were calculated. Our results show that the combination of magneto‐crystalline symmetries and exchange fields leads to various interesting properties, including different values of the saturation field for the magnetization and magnetoresistance curves. Regarding the spin‐wave modes, we observed the presence of Goldstone modes, associated with second‐order phase transitions, resulting from the competition between the Zeeman and biquadratic energies.

The thermoelectric conversion technique has been explored in a broad range of heat-flow sensors. In this context, the Spin Seebeck Effect emerges as an attractive candidate for biosensor applications, not only for the sensibility improvement but also for the power-saving electronic devices development. Here, we investigate the Longitudinal Spin Seebeck Effect in films with a Co 2 FeAl/W bilayer structure grown onto GaAs (100) substrate, systems having induced uniaxial magnetic anisotropy combined with cubic magnetic anisotropy. From numerical calculations, we address the magnetic behavior and thermoelectric response of the films. By comparing experiment and theory, we explore the possibility of modulating a thermoelectric effect by magnetic anisotropy. We show that the thermoelectric voltage curves may be modulated by the association of magnetic anisotropy induction and experimental parameters employed in the LSSE experiment.
