Abstract
Magnetic second-harmonic generation is used for imaging of the orientation of the spins in antiferromagnetic ScMnO3 and HoMnO3 with 10 mum resolution and an accuracy of about 1 degrees. This allows the observation of sample i nhomogeneities and the coexistence of magnetic phases. The method is based on simple geometric arguments which should be applicable to a large variety of magnetic materials. (C) 2000 American Institute of Physics. [S0003-6951 (00)02850-3].
