Future communication technologies require an extension of the frequency band from a few gigahertz (GHz) current to more than 100 GHz. Such high frequencies are not yet possible, as existing magnetic fields in telecommunications can only absorb and absorb microwaves of up to 70 GHz with an active magnetic field. Faced with this gap in knowledge and technology, a team of researchers led by Professor Yoshihiko Togawa of Osaka Metropolitan University entered the helicoidal spin superstructure CSL.

“CSL has a flexible structure in periodicity, which means it can be continuously altered by changing the external magnetic field,” explains Professor Togawa. “The CSL phonode mode, or ring cluster mode – in which CSL kinks rotate jointly in their limited space – allows for a wider range of frequencies than normal ferromagnetic objects.” This CSL phonetic mode has been mentally understood but not detected in testing.

Looking for a CSL phonetic mode, the team experimented with CrNb3S6, a standard magnetic crystal that holds CSL. They first produced CSL on CrNb3S6 and then saw how resonance works under the influence of external magnetic fields. A specially designed microwave circuit is used to detect magnetic resonance signals.

The researchers identified sound effects in three ways, namely “Kittel mode,” “asymmetric mode,” and “multiple resonance modes.” In Kittel mode, similar to what is seen in conventional ferromagnetic objects, the resonance frequency increases only when the magnetic field increases. Creating the required high wavelengths in 6G would need a powerful magnetic field, and CSLs are also not found in asymmetric mode.

In multiple resonance modes, a CSL pony is detected; In contrast to the current magnetic field, the frequency increases automatically when the magnetic field decreases. This unprecedented event will result in a boost of over 100 GHz with a relatively weak magnetic field. This intensification is a much-needed way to achieve 6G performance.
