A magnetic material combining both low losses and strong perpendicular magnetic anisotropy (PMA) was so far missing in the field of magnon-spintronics. The authors here report on Bismuth doped YIG nanometer thick films showing both PMA and low magnet

This article deals with the design and fabrication of compact self-biased $Q$ -band circulators. A pre-oriented substituted strontium hexaferrite that has a high anisotropy field was used to design a planar circulator at 38 GHz. The component has bee

A self-biased CPW circulator with low insertion loss is proposed for operation in the Ku frequency band. A new composition of La-Co substituted hexaferrite with high remanent magnetization and strong magnetocrystalline anisotropy has been developed f

Yttrium Iron Garnet based ferrites are used in non-reciprocal devices like microwave circulators and isolators. The low dielectric and magnetic losses of those materials provide the required properties. The main drawbacks of circulators are their siz

The knowledge of the magnetocrystalline anisotropy is often essential and its determination remains an ambitious challenge. In this article, we propose a new way to measure the anisotropy magnetic field of some substituted lithium ferrites. To achiev

In this paper, we propose the application of polycrystalline lanthanum- and cobalt-substituted strontium hexaferrites in the realization of self-biased circulators. These materials present a high anisotropy field, dependent on the substitution rate,

A study of a very low-loss mm-wave self-biased circulator as a function of temperature is proposed. This device presents, at room temperature and without magnets, maximum insertion losses of 0.52 dB in a 4.1-GHz bandwidth centered at 39 GHz. The evol
