First Ever Electric Circuit Using Magnetic Insulator

integrated circuitHeat loss is one of the biggest barriers to designing efficient electronics. To create more efficient integrated circuits, a team of Dutch and Belgian researchers turned to something that was previously thought to be impossible—they transmitted electric signals using a magnetic insulator.

While conventional electronics use the charge of an electron to transmit a signal, this new technique takes advantage of “spin,” which is a magnetic property of an electron. Previously, creating a circuit using a magnetic insulator was considered impossible because it was impossible to generate strong enough spin waves—perturbations in the magnetic properties of a material caused by an electron with an opposite spin.

Now, instead of trying to generate new spin waves, the researchers tweaked the circuit’s geometry and took advantage of the spin waves that are already present in the material due to thermal fluctuations. They found that when the spin is transferred, heat is also transferred. The researchers concluded that you can heat or cool a circuit by controlling the direction of the magnetization. This new technique could be used to create more efficient integrated circuits in the future.

    Running electronic components off of magnetic spin waves is going to be a serious weakness and vulnerability of HACKING TO DESTROY ELECTRONIC PLATFORMS WITH MANMADE MAGNETIC FORCES, I.E. SABOTAGE! THEIVES ALREADY USE CRIMINAL MAGNETIC DEVICES TO OBTAIN YOUR CREDIT CARD MAGNETIC STRIPS INFORMATION INSIDE YOUR WALLETS! IF this technology is applied, it should only be applied to federal top secret operations! How do we know some magnetic force didn’t effect Robin Williams alleged heart pacer and saying he was a suicide was cover up!?This technology is a future terrorist weapon I’m opposed to! We need to find ways and means to CYBER SECURITY AND THIS IS NOT THE WAY OR MEANS!
