State Switch Is A Key Laser Pointer Innovation

The use of electric current as the state of the spin-valve switch is a key laser pointer innovation. In a polarized current. The spin arrangement of electrons can transfer the spin state of electrons through a magnetosphere. This phenomenon is called spin-transfer torque. The small application of chips has just begun to enter the market, and dozens of companies are working hard to optimize the technology for consumer electronics. One of the challenges is that the chips work at the lowest possible power to ensure that they generate less heat. He explained that how much current is needed to switch to achieve depends on damping, or how long it takes to settle down and enter a new spin state. The measurement of array damping parameters in nanomagnets is very challenging, but the laboratory can use short-pulse laser pointers for this test. He and his collaborators, his graduate students, and the first author. They reported their latest findings and published them in the journal Applied Physics Communications. We can extract damping prototype equipment, measure and display the effect of magnet material performance relative to the manufacturing process. He said that cooperation with Samsung is exciting, and in his laboratory, his students have the opportunity to work at the forefront of emerging technology. This is a completely different type of memory. I hope to see laser pointers used in more applications in the next few years.
