reducing the exchange interaction和spin-mixing conductance是什么意思

"Reducing the exchange interaction" refers to decreasing the strength of the interaction between the spins of particles in a system. In quantum mechanics, particles have an intrinsic property called spin, which is related to their magnetic moment. The exchange interaction is a quantum mechanical phenomenon that arises when two or more particles interact with each other through their spins. Reducing this interaction can have various effects on the behavior of the system, such as altering the magnetic properties or the dynamics of the spins.

"Spin-mixing conductance" refers to the conductance of spin currents between two materials with different spin orientations. Spin currents are currents of spins, which can carry information in addition to charge. The spin-mixing conductance quantifies the efficiency with which spins are transferred between two materials. Reducing the spin-mixing conductance can affect spin transport properties and spin-dependent phenomena in materials and devices
