Embodiment Construction

[0010] The present invention will be further described below with reference to specific examples and accompanying drawings.

[0011] The present invention provides a magnetonic crystal structure for controlling the propagation direction of spin waves, such as figure 1 As shown, it includes a magnetic ion layer 1, and a non-magnetic doped ion layer 2 arranged between the magnetic ion layers 1; according to the spin wave propagates to the non-magnetic doped ion layer 2, it will be quenched, and by controlling the non-magnetic ion layer 2 The ion arrangement of the doped ion layer 2 controls the propagation direction of the spin wave.

[0012] Further, the non-magnetic doped ion layer 2 may include at least two layers, which are arranged between the magnetic ion layers 1 at intervals; in the magnetic ion layer 1 between the non-magnetic doped ion layers 2, the spin waves form stationary The spin wave in the other magnetic ion layer 1 propagates in the opposite direction to the n...

Abstract

The invention provides a magneton crystal structure for controlling the propagating direction of the spin wave, including magnetic ion layers, and non-magnetic doped ion layers arranged between the magnetic ion layers; according to the spin wave propagation to the non-magnetic doped ion layer It will be quenched, and the propagation direction of the spin wave can be controlled by controlling the ion arrangement of the non-magnetic doped ion layer. The present invention sets a non-magnetic doped ion layer in the magnetic ion layer, so that the spin wave will be quenched when it propagates to the non-magnetic doped ion layer, thereby controlling the spin wave by controlling the ion arrangement of the non-magnetic doped ion layer direction of propagation.
