Abstract :
In order to prepare low coercive force MnBi films, a theory is derived, which relates the coercive force Hcto the physical parameters describing the film. To test the theory the experimentally measured temperature dependence of Hcis compared with the theoretically expected one. Improving the crystalline state of the MnBi films it is possible to make films with an Hcof only 45 Oe.
