👉 A cryotron is a type of high-frequency radio transmitter that uses a superconducting coil to generate high-frequency radio waves. The superconductor in a cryotron can be either a ferromagnetic or antiferromagnetic material, depending on whether it aligns with the magnetic field generated by the radio source. When the superconductor is aligned with the magnetic field, the radio waves produced from the radio source will have higher frequencies compared to those produced when they are not aligned.
