Unformatted text preview: (nano meter scale) Especially for MTJ, the thickness of insulator should be thin enough to allow tunneling current to happen. (hundreds angstrom to few nano meters) 3. 2 As nano-particles become smaller, you can achieve higher storage capacity (bit / in2). However if nanoparticle is smaller than certain range, magnetization can flip randomly, or superparamagnetism, which is not desirable for hard drive (As particle become smaller, delta E (=KuV) approaches kT, it starts to become randomized).
