We study magnetic dynamics of yttrium iron garnet (YIG) single crystal thin films using the asymmetrical coplanar wave guides with the double mixer time difference method for the possible applications of highly sensitive magnetic sensors. We achieve the maximum phase change of 50 °/Oe by optimizing the measurement conditions, showing the potential for the detection of bio-magnetic field.
