Abstract :
Noncollinear `umbrella´ structure of the Dy3+ magnetic moments in Dy:YIG is deduced from the satellites in the 57Fe NMR spectrum of this system at 46 K and 77 K. The angle of the umbrella is nearly the same at both temperatures, while the magnitudes of Dy3+ magnetic moments increase with the decreasing temperature
