Abstract

The magnetic parameters (magnetization, uniaxial anisotropy field, uniaxial anisotropy constant, coercive force, domain wall coercive field, domain wall coercive pressure, characteristic material length, domain wall energy density, domain wall width, stripe domain period) of a thin garnet film with the nominal composition Er2EuFe4.3Ga0.7O12 are presented at temperatures between 60 and 300 K. The magnetization passes through zero at T-k = 173.5 K. The parameters that are closely related to the sample magnetization attain extreme magnitudes at T-k as a consequence of the zero net magnetic moment of the material. Other parameters pass through T-k without peculiarities.
