Abstract

Thermomagnetic writing and erasure of binary information in MnBi thin films using 250-psec pulses are described. The ability to write with such short pulses could greatly improve data rates in optical memories. Repeated cycling of a single spot gave inconclusive results concerning possible retardation or inhibition of phase change in MnBi for very short heating pulses.

摘要

描述了使用250皮秒脉冲对MnBi薄膜中的二进制信息进行热磁写入和擦除。用如此短的脉冲进行写入的能力可以极大地提高光存储器中的数据速率。对于非常短的加热脉冲，对单个点的重复循环给出了关于MnBi中可能的相变延迟或抑制的不确定结果。
