Abstract
The magnetism of Co1-xMnx alloys strongly depends on their structure and th e Mn content. An ab initio linearized augmented plane wave (LAPW) method ha s been carried out. to provide the electronic and magnetic structures for t he ice and bcc Co1-xMnx alloys with x = 0.00, 0.25, 0.50, 0.75 and 1.00. By increasing the Mn content, the magnetism of fee Co1-xMnx alloys changes fr om ferromagnetism to ferrimagnetism, finally to antiferromagnetism on the o ther hand, the magnetism of bce Co1-xMnx alloys changes from ferromagnetism to ferrimagnetism. A good agreement is reached between out calculations an d the previous experimental results.
