Description
Summary:The temperature dependences of magnetization of ordered arrays of diamagnetically diluted nanoparticles of superstrong ε-InxFe1-xO3 magnets (x = 0.04, 0.24) in cooling and heating mode in the permanent magnetic fields of different strengths -strong and weak compared to the magnetic anisotropy field -were measured. At temperatures of 150 K for x = 0.04 and 190 K for x = 0.24 a sharp drop in their magnetization is observed, practically to zero. Obtained evidence that the observed magnetic phase transition is accompanied by overturning of magnetization due to spin-reorientation transition of the first kind. The experimental results are described within the magnetodynamic and thermodynamic approaches.
