Figure 3: Magnetic properties of topotactic EuO.
From: High-quality EuO thin films the easy way via topotactic transformation
(a) Spontaneous magnetization M(T) of an EuO film grown on (110) YAlO3 via a topotactic transformation, measured using superconducting quantum interference device magnetometry in zero external field. Both the shape of the M(T) curve and the extracted TC is typical of EuO films. The decrease of M(T) at low temperatures is due to domain effects. (b) M(μ0H) curve of the same sample. The saturation magnetization of the film was determined to be 
μB per Eu. The inset shows a magnified view of the hysteresis curve, which has a coercive field of 50±10 G.
