Abstract
We consider the phenomenon of spin reorientation in uniaxial and biaxial magnets in an external field of arbitrary orientation. The phase diagrams of the corresponding magnetic systems are studied and the trajectories of critical points in the (h, T) phase diagram are found as the angle between the antiferromagnetism vector and the unique axis is varied.
