VOLUME 88 | ISSUE 11 | PAGE 873 Observation of the magnetic domain structure in CuNi thin films at low temperatures I. S. Veshchunov, V. A. Oboznov, A. N. Rossolenko, A. S. Prokofiev, L. Ya. Vinnikov, A. Yu. Rusanov, D. V. Matveev Institute of Solid State Physics RAS, 142432 Chernogolovka, Moscow distr., Russia PACS: 75.60.Ch, 75.70.-i Abstract We report on the first experimental visualization of domain structure in films of weakly ferromagnetic Cu0.47Ni0.53 alloy with different thickness at liquid helium temperatures. Improved high-resolution Bitter decoration technique was used to map the magnetic contrast on the surface of the films well below the Curie temperature T ( K). In contrast to magnetic force microscopy, this technique allowed visualization of the domain structure without its disturbance while the larger areas of the sample were probed. Maze-like domain patterns, typical for perpendicular magnetic anisotropy, were observed. The average domain width was found to be about 100 nm.
