- Abstract
Magnetic phase transition in Fe49Rh51 was studied using wide-field Kerr microscopy. In zero magnetic field, temperature dependences of rotation of polarization plane on the sample surface are obtained. The analysis of the obtained data shows that the temperature of the AFM–FM phase transition is TN, heat = 323.5 K, and that of the reverse FM–AFM phase transition is TN, cool = 317 K. In a magnetic field of 0.5 T, the temperature hysteresis shifts to lower temperatures by 4 K. For the first time ever, the magnetic polar domains with a disordered labyrinthine shape are found on the sample surface.
