SPIN WAVE NONREVERSIBLE CIRCUIT ELEMENT, AND HIGH FREQUENCY NONREVERSIBLE CIRCUIT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a spin wave nonreversible circuit element giving irreversibility to transmission of spin wave.;SOLUTION: A spin wave nonreversible circuit element 10 includes a linear first magnetic material 31, a linear second magnetic material 32, and a discoid magnetic material 40. The discoid magnetic material 40 is disposed between the first magnetic material 31 and second magnetic material 32. The discoid magnetic material 40 is disposed at a position coupled magnetically the first magnetic material 31 and second magnetic material 32. The outer peripheral length of the discoid magnetic material 40 is equal to n/2 (n is a positive integer) of the wavelength of a spin wave to be transmitted.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
