Special Issue Information

Dear Colleagues,

The interplay of spin, charge, and the lattice in quantum materials provides a rich playground for researchers in physics to explore and study. Thin films comprising such materials offer the ability to tune these properties through interface engineering, such as providing strain and mixing different properties at interfaces. This has been enabled through the huge increases in technology in fabricating these materials, as well as the development of probes that enable their study. There are many notable examples where this research has enabled step changes in technology, such as the discovery of giant magneto-resistance and perpendicular anisotropy. In addition, groundbreaking research in thin films has led to novel developments in magnetism, such as the topological spin textures known as skyrmions. Other developments include the ability to influence magnetism by injecting currents through spin orbit torque or indeed by using electric fields by artificially combining materials that have ferromagnetic and ferrolelectric properties. There is also a drive to develop functional antiferromagnet films to take advantage of the higher THz frequency dependence and zero-stray field advantages.   

This Special Issue aims to bring together the most recent advances in this exciting field, celebrating not just the advanced physics behind these novel materials but also their advanced fabrication methods, highly sensitive characterization, and their potential applications in future devices.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access monthly journal published by MDPI.

We have used angled magnetron sputter deposition with and without sample rotation to control the magnetic anisotropy in 20 nm NiFe films. Ferromagnetic resonance spectroscopy, with data analysis using a Bayesian approach, is used to extract material parameters relating to the magnetic anisotropy. When the sample is rotated during growth, only shape anisotropy is present, but when the sample is held fixed, a strong uniaxial anisotropy emerges with in-plane easy axis along the azimuthal direction of the incident atom flux. When the film is deposited in two steps, with an in-plane rotation of 90 degrees between steps, the two orthogonal induced in-plane easy-axes effectively cancel. The analysis approach enables precise and accurate determination of material parameters from ferromagnetic resonance measurements; this demonstrates the ability to precisely control both the direction and strength of uniaxial magnetic anisotropy, which is important in magnetic thin-film device applications.
