Scissors-type trilayer giant magnetoresistive sensor using heusler alloy ferromagnet

Japanese researchers have demonstrated a scissors-type trilayer magnetoresistance device that is promising for narrow readers of ultra-high density hard disk drives (HDD). This device uses an antiferromagnetic interlayer exchange coupling of two Heusler alloy ferromagnetic (FM) layers separated by a thin silver layer. Since the magnetization of the two FM layers rotate around each other like scissors due to the antiferromagnetic coupling, the device is called a scissor-type MR sensor.
