Abstract
Nanometer-sized ferromagnetic tunnel junctions (MTJs) are suitable to investigate the enhancement of tunnel magnetoresistive effect (TMR) by Coulomb blockade effect. A new fabrication process that enables us to shrink the size of MTJs down to the order of 10nm has been developed. MTJs structured by using this process exhibited large TMR ratio of 38%.
