摘要：

This work demonstrates that current magnetic storage density limitations due to superparamagnetic effects can be overcome by thermally assisted writing. Specifically, we write magnetization patterns on thin magnetic films that correspond to storage densities of similar to400 Gbit/in.(2). Simple thermal diffusion considerations predict potential storage densities of >1 Tbit/in.(2) accompanied by recording speeds of >1 GHz. (C) 2004 American Institute of Physics.
