- Аннотация: Spontaneous generation of the electrical voltage in Pr0.6Ca0.4MnO3 single crystal has been found. The charge and orbital ordering in the crystal takes place at T_CO = 240 K, while the antiferromagnetic ordering occurs at T_N = 174 K. As the temperature lowers, spontaneous voltage U increases inilialy slowly (in the temperature range from 300 K to T_CO) and then more rapidly (in the range T_CO - T_N). Starting from T_N, the voltage U increases exponentially and , at 85 K, reaches 115 mV (in the ab plane) and 6.5 mV (along the c axis). The magnetic field differently affects the voltage U in different temperature ranges: it decreases the value of U in the temperature range of 85-130 K and increases in the range 130-240 K. It is assumed that the spontaneous voltage is associated with the existence of ferromagnetic and charge orbital ordered clusters of different topologies in the crystal.
