Abstract

The method includes steps: (1) dissolving Mn(CH3COO)2.4H2O,K2Cr O4 and KMnO4 in acetum fully under room temp, and continuous agitating; (2) Displacing reaction bulb to water bath jar, standing at room temp, coming up by using water bath method; (3) heating up to 318-328 K and keeping it at constant temperature; (4) cooling down to room temp naturally and standing at the state. The invention raises volume of unimolecule (Mn1-xCrx) 12-ac, and quanta storage capacity of crystal greatly, tunneling probability is 1-7.5 times larger than Mnl2-ac molecular magnet.

Description

technical field

[0001] The invention relates to a method for preparing a single-molecule magnet used in a storage device, in particular to a single-molecule magnet (Mn 1-x Cr x ) The preparation method of 12-ac. Background technique

[0002] As microelectronics manufacturing continues to improve, the sophistication of a computer's central processing unit (CPU) silicon chip doubles every 18 months. According to this law, over the past 50 years since the advent of the computer, the computing speed has increased by about 1 billion times, and the line width of the CPU integrated circuit is now as small as 0.2 microns. By 2020 at the latest, the circuit line width will inevitably reach the physical limit of the size of a single molecule, which means that the development of traditional computers will come to an end. However, mankind's pursuit of faster and stronger information processing is never-ending. To enter the more microscopic atomic world, the development of quantum com...
